Hi, we are new to chickens too and did a lot of research. Dry is the key. We used poly panels to block the wind from their open run but you could use them or marine grade clear vinyl on the windows to block the cold air. Seal any gaps where they walk, roost or lay eggs. You do not want any drafts hitting them. Is that a gap in what appears to be the chicken door? You might want to tighten that up if it is. Go in at night and anywhere you can see light, caulk it up! I have a ridge vent that runs along the top of my coop and 2 gable vents, so far no humidity, no dampness so hopefully those vents are enough. It's the draft and humidity that will make them cold, wet and sick. Any insulation you add has to be covered up cuz "chickens". I'm going to add some reflectix to the ceiling w/o covering the ridge vent but that's about it. See my attached pic, I bought a TSC Premium brooder/heater. It gets to 167 on the heater setting but it is radiant heat that warms the body so they have to sit in front of it and mine do. I've been testing all this week the 25 degree weather we are having. It is $60 and uses 193 watts on heater mode. The brooder mode is 53 watts and I think it is 103. I have a Mr Heater vent-free propane heater secured on a shelf for emergencies but I wouldn't leave it running w/o one of us there because it gets hot! I'm now looking at a small, electric, oil radiator heater that someone suggested. Good luck and let us know what you decide to do
