One of my five month old Araucana pullets was stepped on by one of the horses today. Seems that it stepped right on the upper thigh and snapped it right in half. It could be at the joint but it seems to be above that. The leg swings freely. The skin has NOT been broken. She is isolated and is eating well. Does she need to be culled or can i splint a clean break like this and expect it to heal?
