Eggs breathe? Who knew?
in fact they do!
"How do animals, such as chickens, which develop inside an egg outside of their mothers' bodies and therefore do not have umbilical cords, take in oxygen and get rid of carbon dioxide? Bird and reptile eggs have a hard shell. Directly under the shell are two membranes. Between the membranes is a small air cell, also called an air sack, filled with oxygen. As the animal develops it uses the oxygen, which must be replenished, and it also has to release carbon dioxide. How does this happen? Well, if you examine a chicken egg carefully with a magnifying glass, you'll see that there are tiny little holes, called pores, in the shell. In this activity, we'll see how those work to let the developing chick breathe."
