Hello, I am looking for some gender help with this Black Australorp. We have had it for 13 weeks. It was supposed to be only a few days old when we got it. It was from a sexed batch and is supposed to be a pullet. The comb has us concerned. Any help would be greatly appreciated. I have looked at other pictures and tried to compare and looked at the feathers, but this is our first round of chickens and can't determine the gender.
