Farm Innovators 3 gal. Plastic Heated Poultry Fountain HPF-100
Product Review (submitted on December 10, 2013):
Got so tired of the top coming off I glue it on. Then the filler cap broke off the attached lanyard. Then, after all summer, I plug it in last week for the first time and water froze. For 5 chickens, this hasn't done well.
