I've been concerned this winter about the water available for 4 horses (1 belongs to me). I currently care for all four horses in return for having free pasture board next door. The tank heater is, at times, unplugged (this is out of my control) because it trips the breaker to their house which I realize could be very inconvenient. So I'm hoping for tips on keeping water available with temps that are around 0 degrees or below without electricity.
This might sound dumb, but, I read about someone filling water in a hard rubber stock tank and then being able to kick out the ice daily and refilling. So that lead me to think that maybe I could rub vegetable oil/vaseline in the stock tank, then fill with water which would make it easier to kick the ice out an refill daily? Works for snowballs on hooves....so? Just a thought
