My ducks get to free range all day in the summer and go in the barn at night. they live ona dirt floor with hay to sleep on. its easier to clean with dirt, just rake, pick it up and go. in the winter its harder cause they dont go out as much and can make more of a mess. when its snowing a lot i give them their water in the barn, which they spill all over the place. And on days like today, its warm out and the melting snow goes right into the barn, making it muddy and distugusting. The way i look at it is, if i wouldnt live in it, the ducks shouldnt either.
