I have read up and down the pages of this site and others and am still questioning exactly what is happening and how I am supposed to fix it.. or if I need to find the hen being picked on a new home. So these hens all grew up together from the get-go. 3 are Barred Rock, and 2 are Ameriucana.. all of them are 8 months old.. all hens... as of late one of the Ameriucana has been being bullied really badly. I noticed the other day her feathers looked a little bit thinner than usual but didn't think much of it and then the next day I saw her and a lot of her feathers around her neck and other parts of her body have been pulled off, I took her out and inspected her and she doesn't seem ill... just looks like shes been getting beat up and I didnt notice but the other chickens must have not been letting her eat because she lost weight. Once I separated her from the others I fed her and gave her water and she ate and drank right away, I kept her separate for about 2 days and then out of curiosity put her back in the pen with the others and right when I put her in she was attacked by all of them and she took off into the coop. I quickly separated her again from the rest of the hens. Can anyone tell me why they possibly suddenly started doing this to her? Do I need to find her a new home.. or can she eventually go back in the pen with them? and if I do get rid of her will they just pick a new hen to beat up? I'm a first timer with chickens and was appalled over how this randomly started up out of nowhere. They have plenty of room in there pen and are well taken care of.
