A dog today attacked my chickens and 3 are missing, 4 are fine, and 1 I found in the coop with feathers missing from her back. She seems to be doing okay, is walking around with a slightly droopy wing, I think her foot may be a little scratched, but my main concern is her back. Her cushion feathers on her back are all missing, the skin looks fine, but in the middle of her back there is a bloody spot with a little bit of weepy fluid. I don't think the gash is very deep and I have her isolated in the coop for now, I am wondering on advice to keep it clean and keep her alive. Still hoping the others turn up, but not a very high likelihood.
