Someone help!! My rooster has been picking on one Hen in particular. They've been together since day 1 and they are now a year old but lately he has just been beating her up and not letting her down from the perch. Tonight I went out and found her like this. He's obviously grabbed her there and basically ripped a chunk of her head off. What do I do?!?? At first I thought she was maybe his favorite because of the way she looked from obvious mating but now he's really hurt her. I have 1 rooster for 10 hens. I have her separated in my horse barn now with one of the other hens for company. I have vetricyn spray to put on it too but what else can I do? Does she need special diet? I've never dealt with this so any and all suggestions are welcome!!!
