I just went out to check on my Black Australorp hen with 10 six day old chicks and one chick had a wing hanging limp and dragging. They all looked fine this morning so something must have just happened to it. I have the family separated from the flock in a dog crate in the shed so I suspect the mama accidentally injured it with too vigorous scratching for food. I've seen her catch and fling chicks before when she scratches. She's a first time mom and maybe doesn't know better (?). I brought the chick in and put it with a late hatcher that I already had inside (another story!). Should I do something with the wing? Tape it up or something?
