I have been reading through other messages and searches, but I have not found the answer. Our coop is too far from the house to run an extension cord. I have my electric poultry net fencing run off of a solor powered battery. I am trying to find a waterer I can hook up to this unit to keep the water from freezing. We also have our goats fenced in an electric fence powered by a larger solor powered battery. Love to be able to keep their water from freezing too.
