Over the 15-year period, 20.8% of the eggs laid at these nests were lost or never hatched. This falls within the range of 10%-25% of unhatched eggs that is suggested in published research.
Do all eagle eggs hatch?
An egg tooth is formed on the eaglet as it grows inside the egg. It is actually a sharp point on its beak. At the same time, the baby eaglet develops a 'hatching muscle' which actually tips the developing bird's head back. Once it is large enough, the egg tooth will come into contact with the inside surface of the egg.

Lack of egg turning is unlikely to be the cause of these eggs not hatching, as Jackie and Shadow have been tending to the eggs for weeks.
Why do eagle eggs not hatch?
If we assume that a female eagle begins nesting at age 5, and lives until she is 25, she will have 20 years of egg-laying. There is no evidence that a healthy eagle reduces egg-laying as she gets older. So 2 eggs/year X 20 years = 40 eggs in her lifetime.

Why do eagles bury eggs?
Seeing a parent eagle eat an egg is unusual, said Patti Barber, an endangered species biologist for the Pennsylvania Game Commission.
