Well this morning I as able to catch which one is making the sound. It is the little black one. After looking into more info (this is the first time my chickens have hatched any chicks) I'm pretty sure that he is in fact a he. The crow isn't quite right however he acts like a young cockerel. The motions of the crow are rooster perfect and today the crow is a bit more like a real crow. He also gets up on anything to be above the other two. His comb and wattle are developing and they are red. Whereas the other two are not. Also thank you to blairctchickens for the diagram I did notice it does appear a saddle is making its way in. When he gets older I'll update but at this point I think he is a cockerel
