I went to the dollar general and bought a dishpan, plastic tub that you put down into your sink to wash dishes, and filled with builders sand 2/4, topsoil 2/4, and fireplace ash couple of hand fulls . works really well in the coop because of it's high sides, I get less shavings thrown in. I also took a one quart plastic milk jug and cut it so it has about 3 inches in the bottom front, cut up the sides, went across the front leave several inches for stability and leaving the handle in the back--you end up removing about 1/3 of the jug from the front. then my husband made 1 cut in the handle and i poked it Thur the fencing and fill with free choice grit, after they begin to lay you can add another for free choice oyster shell grit. if it will be in a area that gets outside weather take a gallon milk jug and make 2 3 inch diameter holes on each side of the front--that way the chicken can put their heads in but the rain stays out.
