Paper towels are a better option than newspaper and will give the chicks more traction. Chicks don't have very strong muscles at first and have a little more trouble balancing, too. When you watch them at first, they have to kind of brace themselves to stand up some of the time, especially when resting. Paper towels are also more absorbent than newspaper. It's good to use them over or in place of shavings for at least the first few days to a week, so the chicks don't eat the shavings. You could also use them over newspaper at first.
Chicks don't poo that much when they are tiny, but they grow very fast. As they get much larger, the shavings really do a much better job at keeping the smell down. They have a much greater surface area than a sheet of paper.
