I have ducks, first off, and they go inside their coop at night where they eat dinner and have access to water. I am encountering a stinky problem with the area under the waterer staying too moist and the spilled food making horrid odors (they take a mouthful of food and spill it all the way across the floor until they get to the waterer so they can filter out the good stuff I guess). The floor is made of wood slats but the food often doesn't run out like the water does and stays damp. I was thinking of putting sand down there, but anticipating the sand just retaining as much moisture as the food does and leaving me with more of a mess made me want to ask on here first... I also thought of cutting the floor out in that section and putting down hardware cloth under the waterer, I just worry about the hardware cloth catching too much bedding between coop cleanings and the dang neighborhood birds showing up getting free meals from under the coop (which is about a foot off the ground) you can check out the setup on my byc page for specifics. suggestions anyone?
