This is what I just did, got a bucket from Home Depot, used 3 nipples on the bottom (silicone-food safe) and hung it from a bucket hook I got from the feed store. Dropped in a deicer and used a thermocube in the outlet so it will turn on at 35 degrees and shut off at 45 degrees. I'm really hoping this setup works, because we have 4 horses too and I HATE chopping ice out of buckets!! lol I'm hoping to at least make my coop chores a bit easier. The deicer is safe for up to 15 gallons of water and it cost me 34.00 with tax, pricey, but if it works-so worth it!! My only concern is the nipples freezing, but I think if the chickens peck at it and the water is thawed, then wouldn't it be the same concept as throwing water on a frozen car door? That always worked for me when I couldn't get the darn thing open.
