Even though paper towels are sometimes recommend for bedding, they can be slippery for newly hatched chicks to walk on....I use aspen shavings for bedding. If I'm hatching button quail, I only use one sheet of paper towels to spread feed out on, till they catch on to using a feeder.
Another non-slip material is the rubberized cupboard shelving liner. Easy to use and clean up. I use Nutri-Drench for 1 to 2 weeks in their waterers. If any have leg problems, I give them Nutri-Drench full strength, followed by plain water with a small syringe. Just dab it on their beak or side of beak and they will swallow it.
