Wow, you must have an iron stomach to have been able to do that! I can't even think about it without getting sick LOL. I don't have any advice besides basic stuff that everyone's already said like keeping it clean and giving antibiotics, making sure she eats and stays hydrated, etc. But hey, people and other animals do just fine with missing appendages, I don't see why a chicken couldn't. Best of luck to you and your girl, I hope she heals well!
