lol...sorry. I should have clarified. Some people leave areas of the duckhouse with no bedding or just a thin layer of bedding (only putting deep bedding in the nesting areas), and I've heard that being problematic if the floor is linoleum or paint (i.e., slippery). We cover the entire 4'x8' area of our duckhouse with a deep layer of bedding.Duh, of course I need bedding
my run is an omelet run and they are very secure, I have one for my chickens.
With a predator proof run, you should need to lock them into the duckhouse at night. Ducks like to party in the run at night!
