Color vs Breed
There are two things to consider when talking about chickens. Color and breed.
A commonly known chicken is the Barred Rock. Everyone thinks that Barred Rock is the breed. Actually, barred refers to the color. The breed in this example is Plymouth Rock. There are actually many different colored Plymouth Rock chickens... Barred, White, Buff, Silver Penciled, Partridge, Columbian, and Blue. This is true with most chicken breeds... that there are many different colors found in various breeds which include even more colors than I have mentioned.
Just an FYI :)
