I have four little cochin chicks, they are about 6-7 weeks old. I have a sinking feeling that only the gray one is a pullet. But Aside from comb color (which i hear is unreilable with this breed) I dont know what else to look for with cochins. There is a gray, black, buff and lace? chick- just multiple pictures of each. The first is a group shot. Black Lace Cochin? i dont know what you call this color officially. Black Chick Buff chick blue chick shes the only one with a tail right now. the lace one was the first to get a comb anf turn red.
