The best thing I've ever found for chick footing is the rubberized shelf lining - the stuff that is filled with holes. The chicks can walk like mad on it, put newspaper under it to absorb spills, they can eat on it, and you can bleach and dry it to use for your next babies (or use trifectant or oxine). It's brilliant! I'm using it right now in my tub for my tub-turkey, it's that great a footing.
You won't have splay legs on it unless you have a hatch-condition or nutritional problem, never slickness.
Just remove it after three days when they have the land-legs and use bedding.
I'd recommend it for this baby, though - and his buddies.
