My one week old chicks had their first day in the bigger box with pine shavings today. (Previously I'd been using newspaper with papertowel on top). I've noticed them picking at it... but I can't really tell if they're eating it or not. What do you guys think-- should I put some grit in there just in case they are eating it? I'm also having a hard time keeping the shavings out of their food and water. Any suggestions? Thanks everyone, I really appreciate the help!
