What is an Egg?

Commercially available chicken eggs that we are used to seeing and using as food are not fertilized, therefore they are just a reproductive cell that cannot develop into a chicken. Eggs have a calcium carbonate shell that protects the inner albumen (egg white) and the yolk.

A fertilized egg is an embryonic offspring of a bird, reptile, amphibian, platypus and many other animals. If kept at the proper temperature within the proper environment for its species, the egg will hatch into a living creature.
