I recently bought two buff Orpingtons hens. They were out of the run today with my other chickens and my neighbors dog got out and came over. He killed one of my young RIR pullets and at first couldn't find one of my Buffs or my dominique rooster who also was attacked and is fine. I found "Goldie" as my 6 year old named her under a tree stump and returned her to the run. She will hardly move. She stand up but with a distant look on her face. She's drank water and eaten some scratch I gave her but she will not walk around and act normal. Could this be shock? Or could she have internal injuries? I see no signs that the dog grabbed her. But it's not always obvious. Please help!! I have her inside in my lap now to try and help her perk up. But she hardly moves.
