I've read several great posts on here about DIY water heaters for inside the chicken coop. The only thing I haven't seen is a hanging water heater. One option is to place one of the heated cookie tins on top of a 5 gal hanging plastic bucket but would it get hot enough to heat the water at the bottom of the bucket and keep the water nipples from freezing? Another option is to wrap the bucket in heat tape but I'm not sure if the typical plastic buckets you find at home depot would be too thick to allow the heat tape to work well (or possibly start melting the bucket). What do you think would be good options for a hanging water heater? Pictures would be great if you've already created one.
