I like the rubber feed pans for horses, if the water freezed in it, you can just stomp on them and knock the ice iout. I don't use anything fancy, but I'm also home all day to make sure they always have water.Question, what do those of you with larger flocks do about water in the winter? I know there are several threads on the main forum on the subject, but they are all very small waterers. I would really like to find something that will hold at least a couple days worth of water. What do you guys use? Also, do you put the water inside/outside or both in the winter? I have had mine in both, but need to make a choice since I will have to run an extension cord out there and can't run two of them.
