A hawk just tried to get one of my chickens, and the neighbor boy scared it off. There were a few drops of bright red blood on the chickens wing and a very small pool of blood right where she was standing, but I have combed her over and cannot find the source. She is mostly standing in shock, but she has walked a little and is walking fine. She is panting and has a little bit of drips coming from her beak. I have had her in the house for a half hour or so, and we have seen no new blood. Something I should look for? I was all ready to treat a wound, but I can't find one. Is she best back with the flock or alone? Thanks in advance!
