I have several 3 week old black chicks that I'm not sure of their breed. We hatched 3 Black Copper Marans and 2 BCM/EE mixes that look alike. The only difference is their legs, 2 hatched with no feathers, 2 with feathers down their leg and this one only has a tiny patch of feathers above the feet. This one grew feathers as fast as the ones that I know are female but it is a lot bigger than any of the other chicks and the comb makes me think it's a male but I'm always second guessing myself and it has dark gray, almost black eyes. The chick in front is obviously a boy but with no feathers on his legs, the one in question is behind him, looking at the camera wanting a treat.
