I have 11 hens and 1 rooster. Recently the rooster has been really mean to one of the older hens. She's three and he's two years old. He has never been mean or aggressive to me or any person. He chases this poor red hen, runs at her and jumps on her then "kicks" her repeatedly until I break it up. She just sqwats down and flattens herself out and takes it , doesn't try to fight or anything. She is so scared and unhappy, and she used to be one of the older dominant girls. I feel so sorry for her, her life has changed from being happy and healthy to being scared all the time. I can't bear it cuz I just love all my girls. Yesterday he must have got her cornered again, her comb was all bloody and her feathers were all ruffled. I think he hurt her, she walks different, her tail points down not up like the other hens. I separated rooster last nite and put him in solitary (he's in the greenhouse)... not in a cage or anything. I just dont know what to do, cuz other than being mean to that one hen, he is a wonderful beautiful guy! Help!
