Can anyone see any problem using class I sand for my pen. It is down to dirt now and I don't feel like I can clean it very well. I have class I sand (not the real fine sand but a bit more like limestone small flakes), in front of the coop door and I like it very much. It packs down and still has a crumbly top on it. It hoses off pretty well and drains well. I do have a fine sand dust bath for them which they love. I just put the fine sand in my coop and now want something outside that is easy to clean. I also don't think they can dig as much in the class I and maybe it would fill in some of the holes they have made and stay more level. They can still scratch in it so that would not be taken away from them. Boy, the grass was gone in one season and it is pure dirt now! Any input would be greatly appreciated by this relatively new chicken!!
