I beat my head with a 5 gallon bucket with nipples. Bought a nice stock tank heater and it just doesn't keep them thawed so I was at home depot and saw a 5 gallon bucket cooler that fits into the bucket, I put it in the bucket and pressed firmly so the nipples would leave indents then took a 1/2 socket and pushed until I was through the foam to make a hole for each nipple to stick through, I switched over to a aquarium heater that is shatter proof and plugged into a gfci outlet, it sits over the nipples today -5 and it worked all day, the stock tank heater just didn't warm the water enough, the cooler also came with a
lid which I cut a small slit for the cord, I think it keeps much more heat in the bucket. Got my fingers crossed.
