Fall is a normal time of year for chickens to stop laying eggs as the sunlight decreases and they molt, but 7 months is a long time. She's not that old. Another common reason is dietary, though it sounds as if your other chicken is laying. Learn what to do when your chickens stop laying eggs. The final chapter in the oval of life. (This is the sixth and final post in our Raising Chickens 101 beginner series .). Sooner or later, your chickens will A rooster is necessary to have fertilized eggs, but a hen will lay eggs even if no rooster is present. Incubation time for fertilized eggs is 21 days. Days 1-18 require an internal temperature of 99.5 F and a humidity of 50-60%. Days 18-21 require an internal temp of 99.5 and a humidity of 70-80%. A chicken may take from about 5 minutes to an hour to lay her egg.  She will lay an egg a day at approximately the same time. It takes  about 20 hours for an egg to be made … inside her body. That's why  she is limited to one egg per day. It takes 20 hours to make an egg. Chickens are individuals as much as any other animal. Some will lay for two years, then decide to retire. Some will keep laying up to 5 years, then slow down/stop. And some will just slowly decline steadily over the years. Of course breeding vastly affects this. Older hens lay just fine, some of them very nicely. As for how many years, perhaps some long-time chicken lovers can chime in and let us know how their old biddies are doing. ....waiting waiting waiting for the day when my eggs aren't costing me $500 a dozen.... Hens lay approximately 5 eggs per 7 day week. Sperm from a rooster is stored in the hen's oviduct for up to 10 days, so after just a single successful mating many fertilized e … ggs can be laid. Depending on when the hen's last egg was laid, the next egg laid after the hen was mated will most likely be fertile. A chicken may take from about 5 minutes to an hour to lay her egg.  She will lay an egg a day at approximately the same time. It takes  about 20 hours for an egg to be made … inside her body. That's why  she is limited to one egg per day. It takes 20 hours to make an egg. This is another varies with the individual bird and the breed answer. Some chickens lay an egg almost every day, others every 1.5 to 2 days. Younger hens (called pullets if less than one year old) will lay smaller eggs at larger intervals until they reach maturity. Hens lay eggs on the same schedule as without a rooster present. If the rooster is allowed to mingle with the hens, there is a high likelihood that the eggs will be fertilized. This could result in chicks if the eggs are allowed to incubate (either in the nest under the hen or in an egg incubator). On average, pullets, or juvenile hens, start laying eggs at about 6 months of age, depending on the breed. Larger, heavier birds like Wyandottes, Plymouth Rocks and Orpingtons will lay on the later side whereas lighter, smaller breeds like Leghorns, Stars, and Australorps will start laying sooner.  Most hens will start laying between 5-7 months of age. They will lay best at 1 to 2 years of age. All pullets (female chicken under 1 year of age) lay small eggs at first and after a while will lay larger eggs. Younger hens will lay 1 egg every 3-4 days. A hen 30 weeks old can lay 2 eggs every 3 days. Some have been known to lay an egg a day. All breeds have different laying abilities. For more answers to you poultry questions, we have many books and also a video. Chickens usually don't simply stop laying eggs when they get to a certain age, but they will lay fewer as they get older. That said, most laying breeds will lay more or less productively in backyard terms for five or seven years.  For backyard/pet chickens, the peak laying time is the first 3 to 4 years of age. Again, this can vary greatly between individual birds and breeds. Hens don't have a definite end to egg-laying, but eggs become fewer and at greater intervals as they age. Hens lay eggs on the same schedule as without a rooster present. If the rooster is allowed to mingle with the hens, there is a high likelihood that the eggs will be fertilized. This could result in chicks if the eggs are allowed to incubate (either in the nest under the hen or in an egg incubator). Report Abuse. This is a good question. I have 4 healthy chickens which are known for good amount of eggs and started laying at about 5 months old which is the average age and have laid eggs every day ever since for 4/5 years but all chickens are different so it will vary. For your your second question.
