This EE chick hatched 2 days ago. It was pipped for more than 48 hours, then surprisingly hatched on day 23. It has curled toes and a leg problem. I thought it was splayed leg, so I made the hobbles, and cardboard shoes for the feet. Within a few hours, the chick was up and about, hobbling all over the bator. But it's only standing on one leg. Could it be a slipped tendon? I can't tell if the joint is swollen. It looks just like the joint on the good leg. But the bad leg won't straighten all the way. He's getting around pretty well, and I'd rather not cull. Advice on how to treat this? Here's a picture. I temporarily took off his cardboard shoes to make new ones.
