We had our hen hatch babies 2 weeks ago. They have been free-ranging with mama, and just 2 nights ago I started putting them in the coop with the other hens. Up until then, they were in a make-shift chicken tractor at night. This morning we found a baby with her wing almost tore off, down to the muscle, no skin left intact. I think one of the hens must have done it, but Im not sure- it could have been the other chicks or even mama. Chick is acting fine, but I want to know what I can do for first aid for it? We brought it inside and put it in a brooder box, but it was freaking out, trying to fly out of the box and I was worried it would hurt itself even worse by trying to get out. So we put it back outside with mother and babies. Is there anything I can do to help it survive??
