I know this has been posted before, but I came home today to find quite a bit of blood in my chicken run and one of my hens broke her toenail. I cleaned it well , but it is appears like a small piece of tissue or fiber is hanging now from where nail broke. I bandaged her up but what should I do with that part that is still attached. The surrounding nail is broken off 1/4 way down the rest of the nail is intact. She is fine otherwise. Is it tissue?
