Am happy and chagrined to report that my blue dog bowl is working well now. An I starred vacantly at the coop and run it came to me that the extension cord was stilled coiled up. I plugged in a different line, and all the fussing with that orange cord was at the coop end. So I plugged the orange line in to the house, and Voila! Let. There be warm water. Was so inspired that I set up the rope lights, and they were on this morning! Life is good. That was a blond moment for sure.
