We have 4 hens in this coop and recently introduced 4 more hens along with a rooster that came with them. The hens were very aggressive toward each other for about a week then things calmed down. However they quickly ALL became very aggressive toward the rooster. Am I to believe that my chickens were simply rejecting the patriarchal system they were expected to conform to or is there something a lot more likely going on here? He's lost all his tail feathers and in the day since we had seen him last, the hens had started taking chunks of meat from his tail. We have since for his own safety taken him out of that coop and he now lives with the silkies in the auxiliary coop in that run. They love him and he seems to be very affectionate toward them as well. So for now, we seem to have the problem resolved, but the cause remains a mystery to us. Any ideas why the hens seem to have staged a revolt? Thanks a lot folks!
