I had my first chick hatch this morning and it still can't stand. I think something is wrong with its leg. Its not splay legs because I have seem this before and putting chick on towel to get traction didn't help. Its curled in a little with toes curled in. I have read about a sling or boot but am not sure what to try. Or the best way to do either. I really appreciate any opinions. Thank you!
