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).
When an eagle chick is ready to start hatching, it can be heard calling from inside the egg. After it starts calling, it takes the chick about 15 hours to peck the first hole in the egg. There is a special egg tooth on the chick's beak to break through the shell.
