Hello, My winter waterer, that sits on a heated base, is totally rusted. Clearly I need to get a new one as I have now read that any "derusting" products will harm the chickens (the base still works fine). Does anyone have any recommendations for a waterer that I could place on top of the heated base that is (a) easy(ier) to use/fill, (b) not too expensive, and (c) won't deteriorate/break quickly? Also, I should note that I am not handy and would not be able to construct something myself so I would like to purchase. Finally, links to any websites that might sell such a waterer would be much appreciated. Thank you!!!
