They just do! Different breeds lay different-colored eggs. Eggs come in many different colors - light brown, deep chocolate brown, white, off-white, pinkish and even green and blue! Some also lay speckled eggs.

A couple of key facts:

☛ An individual bird's eggs will remain basically the same color all the time.

☛ There can be variation in the shade of egg colors amongst individuals within a breed, but not the base color (brown, white, blue etc.).

☛ One way to tell what color egg a chicken will lay is to look at her earlobe! A hen with a white earlobe will always lay white eggs, whereas hens with red earlobes can lay brown, blue or green eggs.

☛ Araucana and Ameraucana breeds, also known as the "Easter Egg Chickens", famously lay varying shades of green and blue eggs.
