Recently, I decided to embark on the enormous undertaking of replacing the dirty, dusty sand in my run. This involved many, many wheel barrow loads hauling it out and disposing of it some distance away. It was construction sand plus decomposed sandstone and was as dusty as talcum. Then I got out the shop vac and sucked up every last grain and dust particle, leaving just the ugly, ugly packed clay soil, with craters and rocks. As the sand disappeared, so did the chickens. They were spending most of their time outdoors. Yesterday, I began hauling the fresh sand in, one wheel barrow load at a time. I got two sections covered in a few inches of sand, and no sooner did that happen than the chickens returned. Today, I began unloading the second truck load of sand, and I opened the run so the chickens could go out and free range while I worked. No one wanted to leave. They are all lounging around on the new sand in a section I had finished. It's obvious they love their sandy run, and prefer it to bare soil. I prefer it, too. It's been very difficult trying to keep poop picked up when I can't use the litter box scooper.
