I have 3 Black Copper Maran 4 week old baby chicks that I all three look similar and am wondering if it is a pullet or a rooster. I am attaching a photo of one of them. These photos are of just one chick. This one is so docile and friendly. She/he walks right up to me when I walk in the coop and lays at my feet! If you have any photos of your BCM about the same age can you post a photo of it so I have something to compare it to?
