My ducks free range but I leave their pen open during the day so they can go in and out as they like. That keeps the manure down, but I'm not cleaning out their house at all now that the weather is cold.
I just keep putting down fresh straw on top so that the poop underneath starts to break...
Bring the hoses inside...where? In your house or garage? It gets very cold here in Pennsylvania during the winter and my garage is unheated so I would have to carry them into the basement. I'm intrigued by your idea but I can only image how difficult it's going to be to lug the hoses in and out...
