I wrap lower sections of my coop and run during winter with clear tarps and have a sweet coop heater over the roost, and I think it's a great thing to have. I have a few hens are more hardy and don't care about it, but I also have some hens who don't handle -20F cold well love it. Without the heater, I might have a few dead chickens during the coldest nights.I too live in the same general area. I live east of dl about 40 minutes. I am in the middle of a coop build for my chicks that hatched August 1st. I plan on some wall and ceiling insulation. Still debating on getting some type of infrared type heater. Let us know what you come up with !
