Hi, im new to. I think you did the right thing. I once cut my dogs toenail to far, and i did the same thing and she was fine. Which of course doesn't really compare to getting a toenail ripped off. So I would just wait until a scab forms and then very gently clean with a Q-tip and peroxide, you dont want the scab to come off, because it will start bleeding again and might get infected. Sorry about your hen, she should be fine. You should look for whatever she tore her toenail off with and cover it or remove it. Whatever it is, it should have blood on it so just look for blood. Once the cornstarch comes off, maybe it would be good to wrap her toe in a small gauze bandage and tape it with like medical tape.
