I have recently added 3 new lovely ladies to my flock. I am almost positive 1 is a Welsummer, fairly certain 1 is a Black Copper Maran, and the last I just can’t decide! My undetermined is the all black one. They are all roughly 6 months old. I would expect the defining characteristics to be there by now. The previous owner doesn’t know much about the actual breeds of chickens in general.
