I have 7 laying hens, and 3 `.5 month old chicks all drinking out of the same 1 gallon waterer. They go through the whole thing daily. Is this normal, or are they throwing it everywhere, and it just dries up before I can catch it? It seems like a lot of water for only 7 chickens. I need suggestions for a DIY waterer that can hold enough for almost a week or so.
