We have loved the sand on concrete in our run for the last 14 months; it’s now time for some maintenance. What do most of you do when the sand starts stinking? Do we add sand on top of the old stinky sand or remove & replace it? If we remove the sand what do we do with it? I hate the idea moving the odor to another area of our yard, but hate the idea of putting it out in the trash? We live on about a ¼ acre which is a very large lot for the suburb we live in. These are our first chickens; they’re almost 18 months old and going through their first molt. Our run is about 7’ x 10’. The sand has been in it for about 14 months. The intent was to scoop the poop weekly; it’s probably been more like every 2-3 weeks. I expect we haven’t been doing all the necessary maintenance to head off the stink. Advice, Please!
