I got 25 assorted female chicks and most of them I can identify (or believe I can! ) but there are 5 brown ones. And within the 5 there are two variations one lighter and one darker. Their feet are slightly green, do green feet always mean EE? They are a little over a week old. This is chick # 1 and represents the lighter colored chicks. This is chick # 2 that represents the darker ones.
