A raccoon got into our coop last night and there is one hen still alive but she has lost all of her upper beak. She really looks like she is on her last let, and we have her inside in a crate with towels to keep her warm and comfortable. I'm leaning toward putting her out of her misery, but I want to be sure there is absolutely no way she would survive. Do beaks grow back? How would she eat and drink without it? One eye is closed and the other is open. I feel terrible.
