Thanks for the feedback guys. I saw one heated base for sale that said it was for use only with double wall waterers. Is a standard vacuum type waterer considered a double wall waterer? It has the top that lifts off.
I live in New England and am getting ready for my first winter with chickens. I do not have an outside water source in the winter and will need to fill a bcket inside then bring it out to the coop. Are the heated water bases worth money? Do they use a lot of electricity? They sell for about...
