I have two BCM chicks that are 5 weeks old now. One I am 100% certain is a male. He has the copper color around his neck and if he weren't such a punk I'd be admiring his beautiful feathering more, lol. It's the other BCM that has me stumped. I don't know if it's a roo or a pullet. It is solid black with faint flecks of copper on it's wings. It's rounder than the roo is, and fuller in feathering, if that makes sense. It doesn't have any copper on it's neck though. Combs are about the same size, but the little roo's might be just slightly larger. What I am wondering is, does one sex get more of the copper on the neck as they grow? Why are they feathering in so differently if they are the same breed? Anyone have pictures of their BCM's at about 5 weeks of age for comparison? I can't find my camera right now, but I'll look for it tomorrow and try to take pics of both of them. Also, I have two CM's that I believe are both pullets. They seem to be feathering in black. Does the barring show up later? I thought they would feather in barred, like Cochins do. I'm so confused with these birds, lol. Any help would be much appreciated. Thanks!
