I have a deer farm in the mountains of Central Pa and I ran water and power to my pens. I really didn't want to have to break ice everyday just to give my deer water so I went to Tractor Supply spent $39.00 and bought a heated bucket.Let me tell you this thing works, it was 19 degrees with about a 10 below windchill here a day or so ago and my water did not freeze and the deer loved it.The bucket is made so the heater is sandwiched between 2 layers of plastic in the bottom of the bucket and there is no chance of the deer getting jolted.I was really skeptical about this bucket after seeing it but after going thru that cold and it didn't freeze, it made me a believer. It also keeps the snow melted about 3 inches around the entire bucket.
