I use DE,, I have a linoleum flooring then i put a tarp down (this way i can just drag the tarp out when i want to clean and everything is on tarp) I use straw because my girls seem to like it, then i throw DE all over the top toss it a couple times with a pitchfork and im done. I tried Pine shavings before but my girls didnt like it i think it was to slippery for them, thats OK by me because straw is cheaper. Ive only had to clean my coop floor once the summer since i got my girls because there is never anything on the floor BUT my poop board is another matter FULL every morning, but thats ok thats what i wanted them to do. they are never in the coop anyways only to sleep... I did have a mite problem but i think that was from getting 2 new hens and not quarantine them dont think it was from the straw but one never knows... OHHHH and I also use DE in their dust bath area....
