@apryl29 I started using sand and love it. I'm going to try it for the winter this year too. I don't have a way to use a poop board so I make the sand a little deeper under where they roost and add PDZ in those areas too.
I put treats in trays and they promptly pull them out and throw them in the sand. It does act like grit. I put grit out just in case and they don't touch it.
@Suzi18 How does sand work for you in the winter? My coop is raised so I was going to stuff some straw bales under it as a wind break. Thought that would keep the floor a little warmer too.
What's been your experience?
