Hey, I have a flock of 2 RIR and 2 Barnevelder free range hens, last night 1 RIR and 1 Barnevelder went missing. When I got home today I found the missing Barnevelder, but she isn't doing good. She has all of her tail feathers pulled out, and some feathers on her neck are missing. She just stands in a puff ball, and she cant open her right eye. I can't tell where the injury is at, but the right side of her face is bloody and the blood is concentrated by her ear. So i dont know if its interal bleeding or not. I have her in my bedroom in a dog crate with food and water, she wont eat and drink. I did brush some water on her beak, she smacked her beak then walked off in a corner. Do you guys have any advice on how to help her out?
