The heat light in my coop is hard wired. Is there a thermostatically controlled way (like the thermo-cube) to power it? I have 4 hens. The 6x8 coop is insulated and draft free with a large southern window and deep litter. I'm holding out on heat until it gets so cold that I'm losing sleep at night worrying about the girls. I've never had an outdoor pet in this frigid MN climate and I'm entering the season with trepidation. I'd like to have a plan B for when I "chicken out" on braving the cold temperatures. I just thought it might be greener/easier on my electricity bill if it's only running when necessary instead of 24/7. Any advice is appreciated. Cheers!
