I use sand in my run and under my roosting bar. It is so easy to clean, I can't imagine ever changing. I ordered a ton of the construction grade stuff and still have a garbage can full so I was thinking of putting that in the brooder for easy clean up. Just wanted to make sure it's safe for the chicks![]()
