Waterer recommendations

[newbyduckmom]

We have just the non-freezing animal trough type bowls for water for the ducks. Had a self feeder system last summer that my husband set up (hose attached), but it took a dive with the winter. With the advent of summer, and my working all day, I need to get some reliable waterers that will work for the ducks when I cannot be home to change them multlple times a day in hot weather. Curious what folks use?
Haven't found much at local feed stores.

I gave my ducks kiddy pools which unfortunately must be cleaned often. I know they will always have water though. I have 3 pools to keep the fighting down between the ducks & geese

I open range from sun up to sun down, I dug a small pond (7'x7'x 2 1/2 ' deep) plus have 2 kiddie pools and a low bird bath that the ducks go in and drink out of. I also fill a regualr 1 gallon waterer in the coop. I dont worry so much about the waterer in the coop since the pond and pools are here. I currenty have 24 chickens and 9 ducks and so far this set up works for us.
