I have multiple waters, but it is hot hot hot and dry dry dry here.
I have an auto-waterer, which is for piece of mind during the 117 degree weather, but I also have a small horse trough with a fountain in it for ambient cooling and several flat 5 gallon waterers for them to wade in.
Overall, there is probably 8 or 9 pans I dump, rinse, and fill everyday. It takes a few minutes. What takes time is the stupid chick waterers. I HATE screwing those things and flipping them over. There is a 50% chance I will dump one on myself.
