I was cleaning the coop today and I stepped on one of the chicken's toes. Later I noticed that there was blood spots in the coop so I looked over all the hens combs. I finally noticed that one of my chicken's toes was off! It isn't bleeding terribly but the claw is gone along with about a half centimeter of toe. Isolating the chicken isn't really an option because it is winter here and the temperature doesn't generally get above freezing. What should I do. This chicken also lost part of a toe and a nail when it was at its previous owner.
