I have a chick that the left leg is angled 90 degrees out at the knee. It is 8 days old . We found it in an old outbuilding where one of my free range hens laid a clutch. Well the chick seems strong, eats and gets around. The place where she frequently bears weight has a scab on it. We took this chick from the momma hen for its protection as the hen seemed rough on it. I think the leg was actually broken and has now fused in this position. My question...Should I cull her or let nature take its course with our help by providing shelter and care form the flock?
