sinse i'm finally getting a new set in coop and yard instead of free ranging i want to know what to do to keep it clean. i want to get a nonmovable coop and a nice big running yard for my birds but i was reading in story's guide and realized, HOW DO I KEEP THE YARD CLEAN !!!!! i'm sure it will get disgusting evntually if i don't clean it, especiallly with the ducks. i don't want sand or gravle because i can't afford it and its uncomfortable for the birds. pluss the sand will only make it dirtier when it rains. does anyone have any suggestions or tips?
