I give mine fresh swimming water everyday, until it freezes. We dont have a spiggot near the barn, yet, and it is now too cold to hook the hose up to the house and run it to the pasture. So I carry it in 5 gallon buckets from the bathtub, inside, to the barn, about 50 yards. Right now it isnt so bad I make about 5 trips in the morning and then 2 in the afternoon to refill drinking buckets. Good workout but not practical. Once snow and ice hit, any day now, the swimming water will not be liquid and I wont be carrying multilple 5 gallon buckets through 3 feet or more of snow. Until we get the pond dug and the spiggot places, they have to go without swimming in the winter round here.
