So I have a 5x15 foot run set on some grass (soon to be dirt I'm sure) where the chickens live. I have a dashchund who wants to eat them, so the chickens have to be in the run when they are unsupervised... We'll be letting them free range occasionally when we are home. Anyway, it's getting kinda poopy in there. How do I keep that area clean? I have 1.5 feet of hardware cloth as an apron going through both sides, so I don't think a rake would work. Can I hose off the area once in a while? Wondering what others do?
