My chicken's comb got cut on some netting and it started bleeding pretty bad. So, I cleaned of all of the blood and saw that it was only a very small cut. I separated her from my other girls and thought she would be fine in a couple days. But obviously I was wrong. For some reason, her wound keeps opening up again. I put corn starch on it because I know that stops the bleeding, but it didn't help. Then I put pine tar on her comb, but that didn't help either. So what is wrong with her and what can I do to help her?
