how long for an eagle egg to hatch
Bald Eagle Egg Hatching Facts: Eagle eggs hatch one to several days apart depending on when they were laid. Eggs hatch consistently after 35 days of incubation. About 4 days before hatching the chick develops an egg tooth at the top of its bill. From inside the egg the chick pokes a hole in the membrane separating it from the air bubble at the top of the egg shell. Still inside the egg, the chick takes its first breath into the air bubble. and draws in its first breath.
