Sure they will...might take them a minute to get it, but they'll get it.So I didn't stick to the winter water plan. I found I go out to visit my babes enough I might as well just bring out water anyways. I think having a constant supply for summer will be my problem. I'm away more in the summer. I really like the cup and PVC waterers..... BUT will my chickens convert back to the other waterer for winter? I can't use PVC in winter .
