Hello! We have been debating for weeks on if our black Australorp is a roo or hen... It is now 12 weeks old and the comb and wattle look pretty large to me. It is also particularly "protective" of the other hens and the others noticeably follow it around. Issue now is, we just found one of our red hens were completely mutilated, and there's no signs of any outside intruder. We're hoping we don't have an aggressive rooster here are the best pics I could get. Any suggestions/ help is very appreciated!
