Help me please, one of our 6 chickens was attacked by an oppossum. it tried to pull it through the cage, but couldn't so instead it broke its leg and took most of the skin off of the upper leg, below the thigh. It is still living, day 3 after attack. We put hydrogen peroxide diluted with water and antibiotic ointment on the wound, and splinted the leg. she is still eating and drinking but not moving around much. I only saw the possum once, in the dark, don't think it was rabid. Should i euthanized the chicken? what are rabies symptoms in chickens? should i even worry about that?
