The chickens run is dirt and when they dust bathe there crest mounds of dirt and then I have to fill them in by taking the dirt in every hole. They dustbathe by the food so the food gets covered with dirt and rocks and the water turns mud. I know sand won’t help in those ways but it’ll cut down some time with raking. It’ll also cool them down on hot days right? What kind of sand should I use? I heard something about river bank sand or whatever it’s called but idk where to buy any.
