I have a dirt floor coop and cleaning the shavings out of it is such a pain. And shavings are quite expensive. I like the idea of sand, because I could easily mix in DE. But sure how easy it'll be to clean. If I choose sand can I use anykind of sand? Straw seems like it would be very easy to clean up, but wouldn't be able to mix with DE as well, and seems I'd have to clean it out more often. Let me here which you prefer and why.
