Our duckhouse is elevated and has a wooden floor. We use the deep litter method. In the spring we start with a few bags of shavings to cover the whole floor to a couple inches deep. Then we spot clean/stir 2x/day and add straw and more shavings as needed. In the winter and during nesting season, we add more straw for warmth and nests. If it ever begins to smell, I fresh layer of shavings does the trick. We clean out once or twice a year, and all the old bedding goes into the compost.
