I have 24 hens. Blsck Sex links ,Australorps and one dark brahma. I have one hen that appears to be very agressive to the other hens. Now here the queston. I witnessed today the agressive hen doing what a rooster is supposed to do, and that is not crowing , to one of the other hens. There are no significant difference in the appearance of this one and the others. No larger cone, no size difference or anything. Now the agrressive hen also is noisy, but does not crow as a normal rooster. Could this be a rooster and not a hen. I don't have a way to take a picture to post. Sorry! Behavior wise what do you think? I have set four eggs in an incubator to see if they are fertile. I have noticed my eggs have a small bullseye in the yokes, but not a huge one. I guess I'll find out in three weeks! Thanks! Let me know your thoughts.
