A neighbor dog just broke into my pen, killed a rooster, and broke the leg of my favorite hen, Bernie. At first I was worried that she had spinal injuries, but I located the break which is above the joint which is above the foot. It feels VERY broken, I can hear the two bone fragments grinding together when I move the leg. How do I bind this sort of injury?? Right now she's seems to be in shock and is lying on the couch not trying to move. She's just the sweetest chicken I've ever had - please help me help her!
