I have a Black Austrolorp that is crowing like a rooster. However, I have looked at numerous pictures and have read numerous threads about how to tell them apart and everything is telling me I have a hen. I have a total of 5 chickens that are about 19 weeks old and this particular Black Austrolorp has always been the most dominant. I have included pictures and am hoping that someone can tell me definitively if I have a hen or rooster. If it is a hen is it normal for the hen to crow like a rooster?
