My chicken was attacked by my dog yesterday, a great deal of her back feathers near her neck were torn out, and she was bleeding a bit from the area. I tried to nudge her out of where she was hiding, but she kept put, I even tried to get her to come out by guiding her out using her favorite food as a lour, I ended up picking her up and putting her in the coop. She ran over to the water, and seemed okay. But at night, when all the other chickens had already retired to the coop, she was laying down on the floor under the coop. I picked her up and placed her in the coop, but she seemed very unwell.. Today, she was acting like herself, but quite anti-social with the other birds. My chickens are free-ranged so I had them all out for most of the day, and the hurt chicken grazed as normal as ever, except she stayed away from the other birds. Well, all the chickens were in the coop at night, and one of them pecked her on her back where the feathers were torn out! That made me gosh darn mad, so I searched it up on the internet and found out that she shouldn't stay with the other chickens. So she is currently living in the shed (its completely safe from predictors), she has food and water and a bed in the shed, but what else can i do to help her? Is there anything special I can do to help my chicken? What are the chances that she will live? If she lives, how long do you think it will take for her to grow her feathers back? Or will she not get them back until she molts?
