Of the many different chickens, the vast majority lay brown or white eggs.  The Araucana, Ameraucana, and Cream Legbar breeds are all known for their blue eggs, but there are plenty of other variations in the chicken world. The most unusual egg colors include blue, green, pink, chocolate brown, and copper. If you’re looking for even rare egg color, you’ll have to look outside the chicken world entirely. Birds such as quails and peafowl often lay eggs with vibrant colors like green, blue, and even pink.
