Hollywood it's time now for Johnny dollars George read here well good morning George bad morning Johnny now what's the matter you remember to die a killer eccentric only in love animals sure well for the second and for the second time it's disappeared I'm right I hope it's not another singing mouth I'm afraid I take it away dog Johnny and I take it at that you mean a talking dog Oh no exciting adventures of a man with the action packed expense account America's fabulous freelance insurance investigator is truly Johnny dollar I didn't know about mice I do know about dogs and I've never heard one yet that could say anything but rough or maybe you haven't but Michael Murphy had Michael Murphy iron Mike Murphy vice president of Milford Steel Oh what's he got to do with it well he's the former owner of the articulating canine Gellers bought the dog from him according to this application he did hmm when did it happen about three weeks ago first I heard of it was when Gillis called from New York asking for the coverage how much insurance does he have an agreement the maximum we'd allow seventy five hundred seventy five oh no no George that's how he was my time I can't make any commission from a small policy like that why don't you pay him off and forget it I'd like to Johnny but it isn't that simple no no since you found his mouth Gillis thinks you're some kind of a miracle work no pied pipey I mean a pie I'd something anyway the boys upstairs agreed to let you write your own ticket again providing yeah providing you locate the dogs are in the event you don't you pass by Gillis keep him happy so that he doesn't cancel his other policy and if I can't a leader then you wind up with your regular commission and expense account which are auditors will check and double check hmm a real sucker bet but okay George you've got yourself a deal I'm going to come out of two eighty five cents there back to my apartment item three twenty six dollars transportation hybrid in New York City including kids there to the staffer hotel at the time I checked in change my shirt with a thirty I picked up the phone and called the number George we did give me man think of Mr. Gillis please yeah yeah no I had a hunch your father was sitting at your place five fourteen fifty-first feet everyone was there what kind I'll tell you what you got here now hurry right expense account item four one dollar and seventy cents taxis from the stat later the east fifty-first feet address the entrance to the building face toward deep in place and one side of it looked out over the east river I can hear the noise from apartment four C before I step off the elevator I had a good many friends which figured because of a blonde hair and a few other well yeah I put the buzzer and waited I was about to press it again when the door opens for the off down the hall I'm all right I'm going to go on making you to the kitchen but God made it very clear that he wants to see you now and alone alone with that mob in there he's waiting for you in the damage this way how do you get all fine fine just fine like quite a party I sent out the invitations before the pop disappeared I offered to call it off but dad wouldn't let me any special kind of celebration I think so it's to announce my engagement you're a lot of you know who's a lucky man his name is Bill Fisher who's an executive with the powers advertising agency real big time operator just talked one of his clients into putting on a new TV show you know you have all my good wishes all right.  Yeah now exactly when did you notice mean toy was missing. The back and back we should see I'd love me going here locked up taking time but when we got back the door was standing open the front door and I'm not into this door and mean car was gone. Of course he was gone that's what all the fuss is about but the front door was closed it was somebody's coming he's told me that I had sense enough to close the front door when they left you're for sure somebody did steal I know what the things all I know is mean time. Canine animals like it don't grow on trees. Are you mean because of her special talent. Now you're yet to remember because she can talk now Mr Gillers can you honestly say you've heard her speak or a man or dogs can speak but mean I talk just like when being I suppose you know I see you don't believe me who you get mark yourself over here there's tape recorder Oh Mr Gillers if she can talk like you say it's still going to take me a while to kind of get used to the whole country providing we get it back the whole country TV boy what telly a new show called the big shock the first was on tomorrow night what's a marry don't you read the paper anywhere they started advertising about two weeks ago looking for a dog that could say happy hollow dog food is yum yum yummy happy hollow dog that's the company spots and show don't they're going to open a show with the animals say in that slogan you see and today I was going to take me quite on there and let it say it and collect the fifty thousand dollars for the fifty thousand dollars the fifty thousand dollars they're often to give for a dog that can say happy hollow dog food I know I know I know I know anyway when I first heard about this I remembered Mike Murphy said something me over a year ago about having a canine in his can you have to talk to him so I went over there three weeks ago and I bought it was the end of the paper at that time of course it wasn't well how did you know it was going to be Miriam told me how did you know that dress dummy she's fixing the marry the advertising agency he works at it they're the ones that taught the happy hollow people in the put on that show oh I see well you see it was about time I also see that you don't exactly approve a fisher for a son-in-law or I wouldn't say that I don't approve I don't disagree with me if you must marry a stuffed shirt that's her business you know let me play this tape recording for you you're going to hear the sweetest little voice this side of town we made this with Mike Murphy all right good now talk to me pretty now talk pretty canine be quiet what happened she saw a cat you think you still doubt she can talk now I think I'd like to see it with my own eyes have you put an end on the lost and found columns of the papers of course what about the people in this building then I had Mars he's a super put it on for the janitor they call them supers in the city so what's the matter you don't you know any of it I had to put a notice in each apartment tell him to be on the lookout for her but so far nobody said a word and naturally they wouldn't because she's not around here he's been stolen oh no look why would anyone want to steal or they couldn't put stolen maybe it could have been somebody doing it but fight fight who yes like I am Mike Murphy you know he's been saying nasty things to me claim an I cheated him out of mean toy well did you close it to Gillis is there any other possible way she could have gotten out of this role well now there's several huh no no just to think about that that window window yes yes was that open yesterday and I forgot to close it what's down below there nothing nothing nothing but the I continued questioning him making sure he's given me all the facts and after promising to take him along when I visited and like Murphy I said good night and let expense account item five one dollar and seventy cents for a cab back in my hotel the next morning I called Murphy and wangled an invitation to his Long Island home at exactly nine o'clock I was in front of the Gillis apartment yeah you look for me to get it no Mr. Gillis you seen him sure sure when they got to put their back to face oh yeah I see do you pick up the trash and garbage from the apartment every morning back to my job is in your what time do you usually hit this floor at the same time it's an hour about ten nine o'clock either the Gillis is going for breakfast every morning at this time or most every morning what about the day before yesterday did this all when the little one disappeared he was the same hour tell me Morris do you remember seeing anyone on this floor that you know one who did not have a business to hear but there was someone I see the other girl is a person where you stand the way thing at the meeting or who was it you know oh no I don't know his name am I yeah he's such a nice a gentleman and he carried what I know was another person for me to give is I tell them they were out of for their breakfast and he went away you still haven't told me what was more I have a senior who else would bring a Mr. Gillis such a pretty box of such a beautiful gift who else about the gentleman she's shown to marry that too of yours truly Johnny dollar and the ming toy Murphy matters usually keep on ours so I wasn't surprised that Morris the janitor had seen Marion Gillis's pianist they outside the apartment the morning the dog pardon me can I and I disappeared I think Morris first help went back down stairs to my cab when I saw the Gillis is walking toward me from First Avenue morning morning sorry we're late get to Gavin over there I can have a coffee better not let your doctor hear you say that oh no Mary you're ready already waiting for the killer and then let's go but a few things I can't wait to say that Mr. I and Mike Murphy now remember that no second I remember nine yeah they're going to be busy around noon I don't think so far just thought we might have lunch together 21 anywhere you like say 12 30 perfect for you then according to Mr. Gillis and Mike Murphy he didn't know all the ming toy was missing so it was going to be interesting to see his reactions when we told him the movie hall was where the car for a couple of acres near a great bank the main house with a large two-story brick affair with a tack long swimming pool in the kennels behind it or and Mike pursued his hobby of raising Pekinies dog he found Murphy at the camp well Gillis you're lying to them devil you hold your tongue man what do you do or not here anyway I came on to help Mr. Bobby he doesn't know you like I do so I wouldn't be able to tell when you're lying like I can't I suppose you think that's funny darling you know what this man did to me he stole a wonderful little dog right out from under me know you stole her back or what do you mean by that you know what I mean the day after you called me on the phone you saw that ad in the paper for the next day somebody stole mean toy and I'm sure it was you you can't be Irishman for your dirty minded evil old man I have a mind to take a horse with two year for sale oh you did not of course I didn't know you can you say it again I didn't know it was me. Well I whipped you when you're in the steel mills and I can whip him out. Oh Mr. Gillis remember what you thought it said and yes help me. Get yourself back me back to you Mr. Gillis please that's the way I come.  Gillis and I went back to town twelve dollars that's that's the thing Mr. Gillis safely to his apartment I went across town to the twenty one Mary and arrived we were shown to a table and I told her as quickly as I could what had happened at the mercy home. Johnny my father is supposed to get excited I know he knows and I tried to stop him but he wouldn't stop that over losing me to anything else especially something as dangerous as a fight well it might prove to be too much. He's all right believe me I'll call him in a few minutes. This morning when I was waiting for you to come back from breakfast I had a talk with the super a chair. I told you to join a tiny I hope you don't mind no of course not no thanks I've been out all morning with dad Oh I think for the dog that's right any luck I'm not sure excuse us though but what did more have to say Johnny. It wasn't important don't try lying to me Johnny dollar I know you too well. The morning the dog disappeared you were at Marion's apartment weren't you. Of course he wasn't well they before yesterday. No it's sure positive I was in my office all morning what time did you get there remember yes we've been very busy lately getting the big shot ready for the air was about eight forty secretary will swear to them naturally. A couple of phone calls you're right back. I called bill's office spoke to a secretary and of course you'd lie instead of going back to the table I took a cab to my hotel made a couple of more phone calls and waited about 40 minutes later bill Fisher called and asked me to meet him in a bar near Rockefeller Center you like a drink Johnny thanks now right now no I think you'd be thirsty you've been such a busy little boy how do you mean you know what I mean calling my secretary then calling the happy hollow people to find out whose idea it was to advertise offering 50 grand for talking dog I wouldn't be ashamed of having that idea if I were you it's a good one except for one thing it was meant strictly for the publicity value nobody ever heard of a dog that could really talk so I guaranteed them their fifty thousand would be safe. It was tough enough getting the happy hollow people to put a show on TV in the first place they really don't have that kind of money and if they had to pay out the fifty grand on top of everything else well that would be it we lose their account I'd lose my job so what did you do with me and Troy well naturally since she could talk I had to get rid of her you understand that don't you how did you get into the Gillis apartment that was easy I'd been there the night before when I left I slipped the latch to the door wouldn't lock when they went out to breakfast the next morning I went in I was going to put her in that box and carry her out but she put up such a fuss I well I tossed her out the window into the river yes dollar into the East River but what can I do about it after all mean to I was only a dog it wasn't like she was a person what can you do about it I'm not sure but whatever it is I hope it's plenty I left in there and walked down Fixed Avenue when I reached the corner of fifty first I called Marianne and asked her to meet me in a little park near her apartment building somehow I told her as simply and directly as I could well it's kind of funny isn't it John I don't know if I haven't met Bill none of this would ever have happened dad would still be feeling chipper I might have been engaged to somebody else maybe even a nice guy like you and I think it's like this I don't know where I just don't know about a block away from her apartment when we heard the we watched the turn in the fifty-first street then stop then we were running it's not I know are you don't know any such things all right folks all right now keep back in the man room to work on anything they're not going in the building no no they're doing something out there in the middle of the street I haven't said I was there I was there what happened that sounds like a little girl's caught down there under the street under the lady in the drain pipe that goes down to the river are you sure it's a little girl and not a dog you kidding dogs can't talk like that like what like well it sounds like she's trying to say something about a dog food being yum yum yum me if you find the marriage excuse me I joined the power of watermen who had lifted up a manhole cover and put down a ladder it didn't take us long to the street just a couple of a minute and we climb back out of here.  A dollar the dollar you hear she's a happy hallowed dog by George by George boy let me let me down here where is she where is my little sweet that's very much like a lot of that's very much like a lot of this water part of this one I guess you'll have to go down here. What. That means on that. But I think we could be down here to. That's why she disappeared to have her family. He called me Papa Papa. Well, you're not in a good mood, my golly. Well, hereby I got the hood on top. I guess Ming-choy did too. Yes, yes, he must have. Yes, indeed. Look, Johnny, I'm a grandfather. I did tell Gillis exactly how Ming-choy had been helped out of the apartment. All he knew was that Marianne for reasons of her own had called off her engagement to bill. Ming-choy spent a week in bed recovering from her ordeal, and naturally, since Gillis refused to let her appear on TV that night, the $50,000 went unclenched. And, alas, the long-suffering public has yet to hear the dulcet tones of a talking dog named Ming-choy Murphy. Expense account total, including hotel and semettles and transportation back to Hartford, $225.70. Yours truly, Johnny Dollar. To tell you about next week's story. Next week, a vessel that was lost at sea suddenly turns up. Thanks to the true love of my gay young life. Join us, won't you? Yours truly, Johnny Dollar. Johnny Dollar starring Bob Bailey, originates in Hollywood. Written by Charles Smith, it is produced and directed by Jack Brownstone. Heard in our cast were Virginia Gregg, G. Stanley Jones, Joseph Kearn, J. Novello, Bill James, and Howard McNeer. Musical supervision is by Amarigo Marino. Be sure to join us next week. Same time and station for another exciting story of yours truly, Johnny Dollar. This is Dan Coverley speaking.


Let's continue with motion very often in working with any kind of motion you are going to deal with constant circular motion I mean many things can be modeled a circular motion. So Not really any coding again. We're going to do. I just want to show you so just familiar with things that you might see when you are going to Encounter circular motion. So just an image here. We are dealing with constant circular motion. Here's a position vector Now imagine you can see the arrows here. Imagine there is something that you're modeling that is moving on this path Over time it changes at any time t. There's a position vector that points to that That'll be a certain angle away from wherever it started. So it started on the x-axis and a certain time later There'll be an angle change There'll be an angle change. Also note though that this position vector has a magnitude b Because that's just the radius of the circle. That's easy enough to see So just if we look at this image if we just do this the rate of change of that angle with respect to time We call that omega. That's this angular velocity. How many and what is the angular change per second? And that's what we define it as lowercase Greek omega, which is this curly w now I can Do a slight bit of algebra and what I'm getting is just a differential the the the change in theta equals The angular velocity times the change in time Now I can take the indefinite integral of both sides, which will just leave leave me with theta on this side And on this side it'll leave me This omega is a constant. I bring that out. So I'm just left with omega t plus some constant But we're dealing with angles here theta doesn't angle so this constant is actually also an angle and we just call it phi And that's just the initial it turns out just to be the initial angle. So I can start along here I could call this my zero Radians line and I can start on it then phi would be zero But I might start my t equals zero there and if I want to describe that according to this xy coordinate system It has an initial velocity, which will be this angle here, which we'll have to call phi So just putting phi as zero we have the following fact that you've seen this many times circular motion As far as a vector based equation is concerned will be the cosine of something comma the sign of something If you wrote cosine of something comma sign of something that is going to give you counterclockwise rotation And we put the b in front and the b in front there and I'll show you now why that works So constant circular motion That's the rate this this position vector is going to change over time if we model the following b times the cosine of omega t And b times the sign of omega t remembering there. I showed you omega equals Theta, I should say theta equals omega t. So it was the cosine of Theta the sign of theta, but I've just shown you now that it can be rewritten as omega t Let's see if that works. So if I do have a position vector as such And I take the first derivative of that with respect to time If you take the first derivative of that that's going to be negative b Times omega times the sign of omega t And the other side b times omega times the cosine of omega t That's just the first derivative of each of those separately as I said, I'm not using code here. I'm just using these Uh pictures to show you these images how to do it now. What is the magnitude of? The v of t so that means the speed. What is that? well That would just be The square root or the square of this plus the square of that and the square root of all of that If you were to do that You'd see very quickly that all you are left with is omega b because you're going to have a sign squared of omega t Plus a cosine squared of omega t by trigonometric identities those equals one And you're going to have the b squared the square root of b squared is just going to obviously be The square root of negative b squared and the square root of b squared. That's just going to end up with b there Now if If we take the first derivative of the v of t that's going to give us acceleration Or the second derivative of the position vector Then if I had to differentiate that again This is what i'm going to be in end up doing doing and do it on a piece of paper You'll see that's easy to see I can now clearly show that if uh if in here is Is is an The original position vector b cosine omega t. There is a b. There's a cosine omega t There is a b sine omega t. There's a b sine omega t So the only thing we left with is this common Constant omega squared and the negative. So if I bring that out It would be the same as negative omega squared times the original position vector and think about it. Why does Why does if if I were to distribute this negative omega squared into this position vector I'm going to end up with us and it tells us something it tells us now omega squared is a constant And it's the negative of that constant anything squared is going to be positive But there's a negative in front of it. So that's going to be a negative And that shows you if this is the position vector in this direction outwards Then acceleration to keep constant Constant circular motion is going to point in the direct opposite Direction it's going to always be in the direct opposite direction of the position vector And that clearly comes out just from this little bit of Of explanation. So obviously that would be some form of centripetal force Let's see if we can express that centripetal force remember force equals mass times acceleration We've just shown you what acceleration is it is negative omega squared r of t. So I'm just replacing a of t with that Quickly what would be the norm or the magnitude? Of that with in other words just just the size of that force not its direction Well, I just take the norm of this side Now a constant the norm of a constant is just the absolute value of that part So it'll be the absolute value of negative m omega squared And then the magnitude of the r of t Remembering though that means that upside down a little triangle of dots say that means because but because the r of t is that The norm of r of t will be this remember it's the square root of that part squared in that part squared that means this Position vector the norm of this position vector just as we had with velocity before I'm going to have this b squared And I'm going to have the cosine squared of an angle. Oh, there's a little plus missing there They should be a plus the sine squared that equals just one the square root of b squared equals this b Just to show you that the norm the magnitude of the position vector is the radius Ends up b if we write it like this If we write it like this b times the cosine of omega t b times the sine that b is always going to refer to the radius And Because of that remember we had the norm there the absolute value of negative omega Squared it's just m times the mega squared and I've just shown you the r of t Its magnitude is just b. So the magnitude of the centripetal force This is going to be mass times Angle of velocity squared times the radius So again, not very difficult All I wanted to show you is this for you to become familiar with some of these things You're going to see it all over the show and you can always fall back just to see how this was derived and how it all fits In together good


Here's some perspective. The longest man-made structure in the world is the Great Wall of China, and it's just over 21,000 kilometers long. Walking every day, it would take you about a year and a half to walk from one end to the other. The Lagoon Nebula is 312 trillion kilometers across. Walking every day, it would take you over 22 billion years to walk from one end to the other. But knowing the lagoon is 312 trillion kilometers across will give you no sense of how large it will actually appear in the night sky from Earth. The reason being is astronomical objects are at all different distances away. Some like the lagoon are actually much closer to us in the Milky Way than others. For this reason, as an astrophotographer, I talk about deep sky objects almost exclusively in terms of their apparent size, meaning how large they appear in the night sky. The apparent size of objects can be quite non-intuitive. For example, the Lagoon Nebula is three times the width of the moon. And you might be thinking, how could that be right? I see the moon all the time, I've never seen the Lagoon Nebula with my naked eye. Doesn't that mean that it is smaller? Well, no, actually. The moon does appear smaller than the lagoon. But the moon is very, very bright, which is why we can see it all the time. It's bright because it's lit by our sun. Well, the Lagoon Nebula is very dim, not only because it's many light years away, but because it's a diffuse nebula, which by their nature are very dim, being diffuse clouds of gas. So the way, um, anyways, the way we measure apparent size is actually pretty simple. We measure things in something called angular diameter. Let me explain. Imagine yourself out in the desert, no trees, perfect horizons in every direction. You'll be seeing the entire night sky, which can be thought of as a dome, or one half of a celestial sphere, the full sphere being 360 degrees around. So half a sphere is 180 degrees from horizon to horizon. With this in mind, we can define anything that we see in the night sky in terms of angular diameter. For example, the whole big dipper is about 25 degrees across, while the moon is just half a degree across. And remember from earlier that the Lagoon Nebula was three times the width of the moon? So yes, it's about one and a half degrees across. Now a handy way to get to know these measurements and how they actually appear with our eyes is to hold up your hand at arm's length in front of the night sky. And if you make the hang loose sign, that's about 25 degrees. The rock-on sign is about 15 degrees, a closed fist is 10 degrees, the three middle fingers is five degrees, and a single index finger is one degree. So how does all of this help us photographically? Well the first thing you have to understand is the field of view of your system, of your camera and telescope or your camera and lens. Once you know the width and the height of your field of view in degrees or arc minutes, we then know how different objects will fit. And before I show a tool here, let me just explain arc minutes, because I've said that term, but I haven't yet explained it. One arc minute is one sixtieth of one degree, so half a degree is 30 arc minutes. We can break that down further into arc seconds, and arc second is one sixtieth of an arc minute. Typically when we're describing deep sky objects, we use arc minutes because so many of them are under a degree wide. The Lagoon Nebula, which I talked about earlier, is fairly large for a deep sky object at 90 arc minutes across one and a half degrees. Just to give you an idea for some other popular objects, the Ryan Nebula is one degree or sixty arc minutes. Then Dramata Galaxy is a whopping three degrees across at its widest point, or six full moons. Back to field of view though, I'm going to jump into one of my favorite tools for showing this, which is Blackwater Sky's Imaging Toolbox. It's a free web app. I'll put the link in the description. To use it, you're going to go over here and use these icons. I'm going to start with this icon in the top left corner. From here, you can pick your camera and telescope and click Calculate, and then it will update over here, and this green box is your field of view. If we zoom in here on the left hand corner, it can show you that this field of view is 2.6 degrees wide by 1.78 degrees high. Let's say you went into this here and you couldn't find your combination of camera or telescope, or maybe you were using a camera lens, what you can do is just click on this second box if you don't see them represented in that list, and enter these things manually. These would be specs about the camera, and then this is specs about the telescope or lens. Let's say I was using a 200 millimeter lens instead, I just click Calculate, and just like that it updates. This has been another installment of Five Minute Fridays. This week, I'm going to start counting down some of the best Nebulae in the night sky for astrophotographers. Till then, this has been Nico Carver from Nebula Photos, Clear Skies.


This video is part of a series developed for the Sustainable Wildlife Management Program to provide guidance for a successful family poultry production. It focuses on small extensive and extensive scavenging systems, but will also be useful for semi-intensive production systems. Eggs are one of the main products of poultry rearing. They are nutritious and tasty, and a good source of critical nutrients. Egg production is also an important economic activity that provides a livelihood for many people. Eggs are produced for two main purposes. For human consumption, table eggs, and for the production of baby chicks, hatching eggs. Laying Hens Hens start laying eggs between 5 and 7 months of age, depending on the breed and their health condition. After 1 to 2 years, the egg production will start decreasing. The hens can then be sold or eaten. Without any human intervention, a hen will usually lay a few eggs on consecutive days, which is called a clutch. They will then become broody, that is, they will sit on the eggs to incubate them. An egg produced by a hen kept without a male is called a non-fertile egg. A non-fertile egg will keep fresh for a long time. Eggs from a female that has mated with a male bird are fertilized and will produce a chick if the fertilized egg is kept in a warm place and brooded. For an easy egg collection and to protect the eggs against predators, it is recommended to provide nests in the poultry house. The nest should be in a dark, quiet part of the poultry house, usually against a wall to encourage the timely laying of clean eggs. They can be made with baskets, clay pots, cardboard or wooden boxes, with an approximate size of 40 x 20 x 25 cm. They can be filled in with sand, mixed with ashes, up to one-third of depth, and soft materials, for example hay, up to two-thirds. You should have at least one nest for every five hens. After the hen goes broody, you can move her to a cool and quiet place, but make sure to move the nest carefully, preferably at night, so that the hen does not abandon the nest. Ensure that water and some supplementary feed are nearby. If a hen goes broody and you don't want her to, you can place her in a small, separate cage in a cool, shady place. For example, you may need to do it if you do not want to hatch too many new chicks because little feed is available. If only small quantities of chicks are to be hatched, natural incubation by broody hens results in a better hatching percentage than artificial incubation. Since you do not need all eggs to produce chicks, it is better to select the better quality eggs for incubation. Select eggs from your best hens. Avoid excessively large or small eggs. Avoid eggs with cracked or thin shells and keep only the clean eggs for incubation. If you decide to hatch eggs using a mechanical incubator, be sure to handle the eggs carefully before incubation to keep from rupturing the yolk. If any internal damage occurs, the egg will not hatch. Do not plan to store the eggs for more than seven days before incubation and store them in a cool and humid place. Store the eggs with a small and pointed downward and turn the eggs to a new position once daily. Do not wash dirty eggs with water or wipe eggs clean with a damp cloth. This removes the eggs protective coating and exposes it to entry of disease organisms.  This manipulation called candling provides information on whether an embryo is developing inside the fertilized egg and whether this embryo is alive. At six to eight days you can see the shadow of the embryo, which might move in response to the light, as well as a fine net of blood vessels. Remove infertile eggs and eggs with dead embryos from the nest because they will decompose and may break and spoil the fresh eggs under incubation. Eggs hatch after 21 days of incubation. Table eggs The only way to collect clean eggs is to keep the nesting boxes clean.  Collecting eggs daily, especially in the evening, is the best way to prevent these predators from sniffing around at night. Collecting eggs several times a day is even better. It also reduces the risk of the flock eating their own eggs. Eggs are laid with a natural coating over the shell. It protects the eggs from bacteria and controls the amount of water and air that is passed through the shell. Due to this protection, unwashed eggs can be kept in a cool dry place, such as on your counter or in a cabinet. Once an egg is washed with water, it must be refrigerated to prevent them from going bad. If you're not sure how old your eggs are, or if they're safe to eat, you can measure their quality by floating them in water. The broad side of the egg is filled with an air sack. As the egg ages, the natural decomposition of the egg creates more air that fills the sack. The more air is in the sack, the more the egg floats. So to test an egg, place it in a large bowl or glass filled with cold water. If the egg sinks to the bottom, it is fresh and good to eat. An egg that is two to three weeks old will start to rise up off the bottom of the glass. It is still perfectly good to eat, just not quite as fresh. Eggs floating in the water should not be eaten. Fresh eggs can also be distinguished from old ones by the height of the albumen, the white or clear part of the egg, when an uncooked egg is opened and put on a dish. The albumen of fresh eggs is relatively high. The half is high as the egg yolk. In older eggs, the albumen becomes watering and lies flat on the plate, and the egg yolk is also flatter. Take home messages. Include nests in the poultry house and clean them regularly. Fertilized eggs will produce chicks if brooded, either by the hen or artificially by an incubator. If only small quantities of chicks are to be hatched, natural incubation by broody hens will give better results. Broody hens need a cool and quiet place. Remember to collect eggs several times a day, especially in the evening.
