I was actually thinking of putting a little dirt box in their box, as I have to watch them when they are out and they are still too young to stay out all night. Right now they are just in a box in my living room with a light at night and during the day I put them in a hutch outside for a few hours. Just started doing that, but they would be happy if they could play in dirt while in hutch. I have been on vacation this week, but next week when I go back to work I am going to feel sorry for them being in their box all day. And now rain is suppose to come this weekend and I'm not sure yet if it will be too cold to let them stay outside during the day unless I can somehow rig a light in the hutch.
