HELP. Our coop is far away, and I can't seem to find a product that will provide heat. Solar is apparently too expensive and/or complex at this point, and battery operated impractical. We are considering running electric underground or simply an extension cord, but our dog loves to chew plastic/rubber and she loves to dig for gophers (we have them in abundance). At this point, I think they will be in our laundry room for starters, but that can of course only last so long. ANY ideas? I'd sure appreciate any suggestions. Thanks So Much.
