I had a chicken attacked this morning by something. We found her in the tall grass, hiding. She has a laceration across her back almost from wing to wing about 1/4 wide. She has a couple puncture wounds and some bruising on her thigh as well. She is limping and holding her wing out. She seems weak and fell over on her side when I tried to move her in the cage. She is up on her feet now, but wings out. We cleared away the loose feathers and put blue kote on all her wounds. I have her in a dog crate. She is drinking and eating. What else should I do? Should we trim the feathers back away from her wound, so it can breath? What are her chances?
