As you may be able to see, 1 of the 4 has a much more developed tail and the other 3 have tails that are sprouting. The one with darker (blackish) spots on the comb is the one with the pointier tail. I don't know if this means that I have 3 pullets and 1 cockerel, or 3 roos-to-be and 1 pullet. My luck.... 1 pullet. :-/ Nonetheless, they sure are cute!
