I have a 8 1/2 week old Wellbar hen that “high steps” when she walks and has one metatarsal pad that is ever so slightly larger. There are no lesions that I can find. She walks but is very quick to sit, choosing your sit for her water and for her food. She seems more “svelt” than our other chickens but she is the only one we have of this breed. Could this be really early bumblefoot? If so any suggestions on how to help her?
