Our chickens were attached by a neighborhood dog (Jack Russell Terrier) two days ago. I pulled the dog off of Suzie, just as he pinned her. I can't tell what her injuries are. Missing lots of tail feathers, but otherwise seems unharmed. She was able to get up and walk around afterwards, but is not eating, pooping, or mixing with the other hens. We secluded her overnight last night, because the other hens were pecking her. But she is not eating or pooping at all. Please give advice! Suzie is only 6 months old, a Speckled Sussex. Thanks for any help you can give.
