Farm Innovators 3 gal. Plastic Heated Poultry Fountain HPF-100
Product Review (submitted on February 6, 2014):
This is the first winter we have had chickens, With the unusually cold temps we've been having here in middle Tennessee, it was almost impossible to keep their water from freezing even with a heat lamp. After searching on the internet, I finally located this heated fountain and, boy, am I glad I did. Even when we had -2 degrees, the water never froze. Great product!
