The other thing that helps is to put a wooden base or bricks in the brooder, put paper towels over it for easier cleanup, and the water on top of it. The base needs to be large enough that it won't tip over with their antics. That helps keep the shavings out of the water.
Newspaper on very bottom of brooder, covered by pine shavings, covered by nubbly paper towels. After 3-4 days I take up the paper towels. At about a week I put a brick or something under the feeder and waterer to keep them up out of the litter - at about chick back height.
