Welcome to BYC!I had some Silkies a long tie ago that a dog got to and ate the top of the back, exposing organs inside. Just as bad as you have here. I bandaged it up with gauze which i had put neosporin on the gauze then used the sticky wrap for pets to wrap it to keep it in place. I keep it clean, etc...and I was amazed that the bird ended up completely fine!
