We just "remodeled" our coop and run with sand. Our coop is down a flight of stairs in the backyard and hard to access, so we ordered bags of non-sandbox construction sand from Lowe's and had it delivered. We then carried the 50lb bags down to the coop. It was pretty labor-intensive and the bags were inexpensive, but not as cheap as having non-bagged sand delivered, although so far we love the sand. It looks great (so much cleaner than wood chips, which look messy imho) and we use a big cat letterbox scoop to clean it. My only concern is that BYCers report that when it starts raining the sand begins smelling really bad. I try to clean ours every day (easy with the litter scoop), so hopefully that won't be the case. Good luck!
