When bird are young do they breath throw the ells

There is an air sack inside the egg that helps the bird breathe oxygen inside the egg.

Explanation:

When birds are young do they breathe through the eggs?

When the eggs are laid by the mother they're very warm, and as they cool the material inside the egg shrinks a little bit. The two membranes pull apart a little and create a small pocket or sack of air. As the developing bird grows, it breathes in oxygen from the air sack and exhales carbon dioxide.

Hope this helps!!
