I will have to get that a try. I never considered dust bathing for chickens. I guess the little patches of dirt covered in feathers in the run make sense now!I have a kiddie pool with sand in it for my girls to take dust baths in. I drilled holes in the bottom so water can drain out when needed. My girls love it. I have to put more sand in it a couple of times a year because they kick it all out after awhile.
