Her in coastal VA we generally have cold with little snow or extreme cold for any great length of time. Jan and Feb is our coldest. So I have heated water tubs, buckets, etc. And use if it's going to be several days....unusual. They are expensive to run. But sometimes needed. More often, it's breaking frozen top water, adding hot to it. Length of cold and actual temps guide my handling. If all day low temps that prevent thawing, I treat different than ice in morning. Some years I fill a heated tub and dip from it...some I carry a few jugs of hot from house. I have water and electric in most barns and underground water lines, with spigots covered. I did buy one of those flex, lightweight hoses a few yrs back. Easier to carry in and out if snow, extreme cold, to use at outer spigots...taking inside to keep thawed. No matter, cold is difficult for us and animals for water!
