Breeding bald eagles typically lay one to three eggs once a year and they hatch after about 35 days of incubation. Hunting, egg sitting, eaglet feeding and brooding duties are shared by both parents. The young eagles begin flying three months after hatching and are on their own about one month later.
This is called a 'brood patch'. Different birds sit on their eggs for different lengths of time. Bigger birds lay bigger eggs which take longer to hatch. Blue tits incubate their eggs for two weeks but swans sit on theirs for nearly six weeks!Most birds lay one egg a day until the eggs are all laid. Some birds lay up to 15 eggs but others lay only one.But the parent birds do not start to incubate the eggs until they are all laid.In some birds, only the mother sits on the eggs.ost birds lay one egg a day until the eggs are all laid.
