OK, I am wondering. I see they need "clean water" all over the place here. But I also see people with the 5 gallon buckets that they don't have to fill for a week. I have been cleaning mine daily due to chicken dust. Am I going over board??? How clean does it need to be? Here is my set up. The 5 gallon bucket is attached to a watering bowl. I turn it on to clean it & then fill it. It use to be always on, but hte hose developed bulges, so I stopped that. The slef over it prevents most of the poop from getting in it.
