I'll look up that post.
Coturnix eggs chicks stuck in shell - Page 2
I use a small round bandaid cut in half to fix curled toes, although must be doing something right as haven't had any lately. Just sandwich the toes flat between the bandaid. The one in my avatar had curled toes on one foot and splayed legs. Pic demonstrates how it was fixed. Often only needs to be on for 24hours. You will probably need someone to hold the chick while you do it as it is pretty fiddly.
