11-12 weeks of age
Why do Bald Eagles have such big, strong nests when they have only two small eggs? Bald Eagles are about 3 feet (90 centimeters) from their head to their tail and before the nestlings leave the nest, they become as large as their parents and need a lot of room for their 6 foot (1.8 metre) wingspan. The first egg laid will be the first egg to hatch and therefore the oldest eaglet may be a little larger and better able to fight for food than the younger ones. How long do the nestlings stay in the nest? When do they learn to fly? Eaglets stay in the nest and are fed by their parents for 12 to 14 weeks. The chick will measure 4 to 5 inches at hatching and weigh only a matter of ounces. Bald eagles incubate their eggs for about 35 days. They begin incubation as soon as the first egg is laid. The second egg usually appears within 36 to 72 hours after the first. Occasionally a clutch of 3 eggs will be produced.  Answered Most Recently.

After about 6 weeks of being with their Parents the Baby Eagles are pushed out of their nest to go on their own. Actually, baby eagles, or eaglets, stay in the nest until at least 11-12 weeks of age. The parents feed the babies until they leave the nest permanently. Even if the eaglets can fly well, they quite often keep coming back to the nest or stay in the area while the parents continue to feed them. Only occasionally will the parents 'kick a baby' out of the nest. Eggs are laid a few days apart and consequently hatch in the order they were laid. Female eaglets tend to be larger than their male counterparts. Like most birds of prey, the female adult is also larger than the male. Adult eagles range from 33-35 inches long for males and 35-37 inches for females. See photos 3-5. Before baby eaglets hatch, there is always one parent in the nest to incubate the eggs and protect them from predators. The parents share incubation obligations for about 35 days. Q. About how long does it take for the bald eagle's eggs to hatch and how long until it can fly? A. It takes 35 days to hatch, then young in nest 10-12 weeks more unti lthey fledge (fly from nest). Q. How old are they before young eagles can fly? A. At 10-12 weeks, when they leave their nest. Q. When do eagles learn to fly and how? A. At between 10-12 weeks as they first leave the nest (fledge), and then with more and more practice to and from the nest and surrounding trees over the next month or two. Q. Out of twenty eaglets, how many will live to be adults? A. This varies with the population in question. From our work releasing eagles in New York, about 2.5 adults would survive for every 20 (1 in 8). Mortality is highest for eagles in their first year of life, especially their first six months. From the time they hatch, it takes eagles 65 to 75 days to get ready to fly. During this time, their white downy coats are replaced by darker feathers. When there are young eagles in the nest, both of the parents have to do a lot of hunting. The chicks never seem to get enough to eat, and their parents are constantly taking off to look for food. Baby eagles don't drink milk like baby humans. Instead, their parents give them little bits of meat. All eagle parents take very good care of their young, and this includes feeding the eaglets all the food they can eat. As a result, the chicks grow very rapidly. Golden eagles, for example, weigh only about three ounces at birth (85 grams). The chick will measure 4 to 5 inches at hatching and weigh only a matter of ounces. Bald eagles incubate their eggs for about 35 days. They begin incubation as soon as the first egg is laid. The second egg usually appears within 36 to 72 hours after the first. Occasionally a clutch of 3 eggs will be produced.
