Quackers Mama - I don't know much about caring for ducks or their behaviors, other than that they can apparently be messy. I would guess success would likely depend on how wet/dry your climate is and how many birds you have per square foot. Maybe someone with more experience can chime in...
I do what Beekissed does.
I was just giggling with my husband over dinner this evening about when people talk about A or B or XYZ being easy to clean.
Like Beekissed, I DON'T NEED TO CLEAN. Really. My chicken whole run is a lovely compost pile. I throw my leaves, weeds, grass clippings...
