What I do right now is (on a plywood floor) have a plastic drop cloth tacked down. I covered that with a canvas drop cloth then straw on top. The plastic keeps the floor dry and clean, the canvas is EASY to clean when I change out the straw and can be taken out and changed as needed (and gives a nice surface feel). I really like straw, I love the way it smells and my chickens look so cute carrying pieces of it in their beaks.
