My chickens are about 10 weeks old. I move them into a coop two weeks ago and everyone was doing well. I notice this morning that one of my chicks is walking strange. It looks like she is having trouble keeping herself balanced, she is taking small steps. She is keeping up with the rest of them just fine and eats well, overall looking healthy. Just that wobble that is concerning. I read that a vitamin deficiency can cause issues with balance. Already checked her feet for bumble foot but nothing like that. Anyone can help?
