Thursday night is supposed to be 37 degrees here. Would any of you worry about frozen waterers with that temperature? I don't think I need to worry at all about leaving a light on anymore for the waterer, but I want to be sure. What would you do?
I don't know about where you live, but here in Yakima, our water doesn't freeze until the air temp is 32 degrees or lower. I think you'll be just fine with 37 degree temps.
