Went out to the coop for nightly chores and found one of my hens with blood on her side. Upon further inspection I found a very large (about the size of my palm) open area under her right wing. My guess in one of the boys was having too much fun with her and ripped her side open. I can see her muscle, but she is not hardly bleeding at all. I have put her in a large dog carrier with clean bedding some food and water for now until I figure out what more to do with her. Is this something I can take care of on my own or should I seek help from the local vet? I know it's not the best picture, but she wasn't happy when my brother tried to pick her up. The rooster attacked him at the same time. He was messin' with one of his ladies.
