It wasn't splay leg, nor crooked toes. The feet were curled inwards and the chicks were waddling on their hocks. One got flipped over by mama bird and was unable to even flip itself back over. These two chicks took an awfully long time to hatch, they were the last ones to do so actually. Maybe being in the egg so long had to do with it? I've ran into this problem a few times over the years, and I haven't been able to find much info about it. I've tried splinting on problem chicks like these before, but it did no good and they eventually got worse, their poor little hocks swelled and got raw from them scooting around on them and had to be culled.We're they not splintable? What were the issues?
