I got one of those galvanized double-walled waterers, thinking that, come fall, I would get the metal heater bottom for it. We live in NH and below zero temps in the winter make heated waterers a necessity. We have plastic electrically heated buckets for our goats and those work great. This blankety galvanized waterer is a pain in the butt (chicken butt!) I have to check it at least 2-3 times a day to make sure that the water is actually being let into the little tray. Here's my question... Is there some way to adjust this thing so I don't have to buy a whole new thing. If not, I saw a plastic waterer online at Stromberg's that looked good and it has a separate heated base that is available also. Sure is mighty expensive though. The one that is an all-in-one plug in model someone said is a pain to fill especially in the winter. What to do?
