I have a hen that was given to me by my sister in law. She got caught between the house and the fence over there, and broke her leg at the knee. Her toes are warm, but she cant move the leg below her knee. She does hobble around and is otherwise in great health. Shes about a year old if not 2. We have put a temporary splint on her leg for now. Should i wait and see how it heals or should i go ahead and cull her??
