When I get new chicks I first dip their beaks in the water and then set them down IN their food tray. I've yet to have a chick that didn't start eating immediately. After that they're free to wander where they want in their brooder. I don't put paper towels down and have never had a problem with them eating shavings. Picking a piece of shavings up in their beak to check it out, sure - all babies put things in their mouth to check em out - but never to eat them.
