I live in south centrail PA. The winters are not usually to bad but last winter it was single digits for a good long time. I you use a metal chicken waterer or also called a sinlge metal fountain. What do you all use for waterers and how do you keep them from freezing. I usually use a heated metal base. What about the dog bowls>? or just using rubber pans and nocking the water out each morning and night..... any suggestions are helpfull.
