Is a Bird Egg an Embryo

Anatomy. All bird eggs contain the following components: The embryo is the immature developing chick. The amnion is a membrane that initially covers the embryo and eventually fills with amniotic fluid, provides the embryo with protection against shock from movement.

How do bird embryos breathe?

As the developing chick grows it uses the oxygen from the air sack and replaces it with carbon dioxide. The tiny pores in the shell allow the carbon dioxide to escape and fresh air to get in. The chicken egg has more than 7,000 pores in its shell to allow this to happen!
