Hi gang. I have 16 two day old CX chicks. They are eating chick starter and drinking lots of water, they all seem pretty healthy. My question is: I have about two inches of pine shavings under them but I put an old sheet on top of the shavings just for the first few days so they don't eat the shavings. The sheet is pretty messy after a day and a half, should I just let them onto the shavings or use another piece of old sheet for another day or so. What do other chick mom's do?
