I use sand as well. I used 2 50pound bags of play sand $3.43ea and 3 60pound bags of all purpose sand $3.53ea from Home Depot. It filled my structure 4x8x6 perfectly. Plus used sweet PDZ and DE. I put a small amount on the in the poop board, just enough for scooping. It stayed real nice, no smell. I scoop regular and only takes about 30 minutes. Lately though we've had rainy days. I'm still happy because its not a muddy mess. But it hasn't dried out due to frequent rain showers. Don't get me wrong, I'm still very happy. It's just they don't have a chance to dust bathe. So I'll probably fill a rubber drain pan with sand and put it in the corner of the run where there is a wall that should help keep it dry. The structure is on concrete and when it rains, water soaks up into the sand keeping all 4 corners moist. So the pan should be dry. Mine is an enclosed run/coop. Ladder leads them to the nest roost area. Thanks to my hubby's wood work skills, the nest house is nice and dry. If there were to be a long spell between rain I would mix up the sand turn it all over and it would dry back out to loose sand. But with chance of showers in the upcoming days I'm not going to bother. Adding the pan of sand should take care of their dust bathing needs. So, bottom line is I love the sand. No hard labor, no odor, no flies.
