I put down some straw last week and it started off to look great. The chickens enjoyed it and kept it nice and neat. This was it last week. http://flic.kr/p/9aYU8M Now, after one light rainfall, the run is smelly, horid, soaking wet, nasty and muddy. GAH! Does sand really work well to keep it dry?? I've been wanting to put it down for a while now but haven't found the time. I'm thinking some nice gravel-like sand?
