Last Monday, one of our pullets recieved a leg or hip injury. We immobilized it for 4 days and kept her seperated from the coop. Last night we reintroduced her to the other chicks. She is able to get around but holds her leg up and wont walk on it. She is eating and drinking fine. Will this heal on its own? Is there anything else we can do to help her in mending her injury?
