I have a chicken fountain and I love it. I can't go back to filling a gross bucket this winter. My plan is to use gravity feed and heat the water. My question is can I use the electric heater base that used to go under my metal water bucket with a 5 gallon plastic bucket (lowes type bucket)? The heater is similar to this http://www.walmart.com/ip/21799162?...31143116&wl4=&wl5=pla&wl6=50567295276&veh=sem .
