If your chickens don't have access to dirt you can put some loamy dry soil in a big pot, maybe 16 inches diameter and 6 inches deep and they will have fun scratching and throwing the dirt on themselves. It's very amusing to watch!
Will play sand work? do i need to put anything else in to help with mites fleas ticks and so forth also what is de and do i need that and where would i get it?
I took a plastic bin designed to mix concrete in and mixed some DE in with a bag of play sand......wow do my chickies love it!! They crack me up in that thing! Although they have now bathed so much that the container is only about 1/2 of what is used to be....I guess I will have to add more. I didn't realize that when I did it - but they even get in there together sometimes and go to town rolling and kicking up that sand.....
DE is kinda hard to find......I found a place in my state that carried it for an okay price through the perma-guard website. cost as much to ship it as it did for the bag.....lol. But it's worth it - I love the stuff - it goes in their food, in the coop and the run and the nests and the dust bath.
