Noah is there anything like a dog or snake that could have attacked him?
Sometimes mine gets some sticky grass that cuts kind of like a paper cut. Is he able to be handled so you can look at it closer? I usually use neosporin for small cuts. If you see two punctures then I would suggest snake bite and for that a definate trip to the vet is needed. anything that is small though I handle myself. Lemon juice cauterises (spelling?) blood if it has not clotted yet.
I can handle him!!! He also has it inside his mouth so would you really put neosporin on it or any medication? I also think that it has probably clotted by now but I want to know for future uses! I think that he probably just cut it somewhere while they were in the coop, we keep them in two dog kennels connected so he might have cut it there?
I would not put it inside his mouth... but I had one that had her bill scratched up by a cat. I put the Neo on it and she healed up pretty quickly. A goose has a high temp which is pretty quick to kill germs off of. Small scrapes and scratches usually heal quickly from what I have noticed.
