My husband had some wood in the chicken coop and it blew over onto a month old chick. I think it's leg is broken. I have it wrapped up in a towel in my lap. It's not moving, I think he could be in shock. It still chirps but mostly sits with it's eyes closed. When resting, it won't lie on the right side of is body at all. he won't stand or walk, even one legged. Wings are not broken. I know I need to keep it warm but what else can or should I do?
