Baby eagles are called eaglets or chicks. Bald eagle chicks hatch out of round or oval eggs that have been incubated for approximately 35 days. They weigh about 2 ounces when they're born and can gain 6 ounces of weight every day.
Golden eaglets hatch after about 42 days of incubation. They're brooded by their mother, but both parents feed them. They start to fly when they're about 10 weeks old but are still fed by their parents for up to two and a half months after that. Wedge-tail eaglets are born with white down and need six years before they attain adult plumage.
