Okay...update of the water saga at the KettermanHillCoop... Insulation board didn't match up to the prolonged arctic freeze. So...I bought a heated dog bowl and inverted it. Then set the gravity waterer on top of the upside down dog bowl. It worked like a charm.
I'm just infuriated that we all even have to go through all this nonsense of inventing ways to keep the water from freezing. Why can't Farm Innovators (the folks making those heated gravity waterers) just bump up the dang wattage???? They obviously don't work when it gets chuckin' freezing out. Take the design of the dang dog bowl and make it the bottom of the waterer!
Rant over...
