One of our barred rock chicks has what we thought was curly toe. It's leg was paralyzed, it couldn't pull it in, it was left sticking out at an odd angle. It's toes curled upwards. We poured b12 super concentrate into the water. We also put it on the chick's foot/leg. It helped a little, but it never got better. We gave them lettuce, sprouted wheat, and a little bit of carrot. After two weeks, the chick isn't better. It's gone thru ups and downs, getting better, then worse, then a little better.... It was bad again today. We're wondering if it's sprained or something, except for the curled toes. We're feeding DuMore chick food, and this one is the only one that has it. The rest are healthy.
