I have started to think of winter plans and this year I have ELECTRICITY out at my chicken coop SO I was wondering what heated waterer is the best. I have seen the one at Tractor Supply that I think is 3 gallons for like 4o dollars. It is plastic. Is there a better one? Is there one you would recommend. I have heard of the ones people make on here but I just really dont have the time to do it. Is there another base I could buy instead? INFO PLEASE!!!! THANKS.
