I have a barn with a dirt floor. After thaw in the spring, it is stripped completely down to dirt, allowed to dry, put a layer of stall dry down, then a light layer of bedding. I repeat this in the fall - mid October or so but let the bedding stack up till spring. Unless one of my teenagers pisses me off (or anounces that they are bored), then the buck pen might get an extra cleaning as long as it isn't too cold.
I do regularly clean off their sleep benches & scoop up any areas w/a lot of berries conglomerating.
