I use sand inside the chicken coop. We had a big pile of sand leftover from construction, so I used it inside the coop. The chickens are let out into a moveable fence run every day, so they aren't on the sand all the time. I scoop out the poo with a long-handled kitty litter scoop I purchased from Amazon. I have a big tub of sand inside the coop with a little food-grade DE mixed in it for the chickens. The quail have a small tub of the sand mixture in their pen inside my out-building as well. (They are not near the chickens.)
