I’ve been treating my black Astrolorp t for sour crop for about two weeks now. So she has been away from the flock. I let her free range with the other chickens today and she was asserting her dominance. We also noticed that her tail feathers look longer than the rest of the hands. She’s about 26 weeks old and I have not heard any crowing, but the tail feathers make me second-guess whether or not she is actually a rooster.
