I'm in North Texas. For the first time since they became hens my birds are in their coop, not on the roost in the run, and they are already looking cold. Temp won't clear freezing til Friday, and we have high wind. I put big windows on the sides for ventilation in the summer, 3 inch high wide windows up near the peek, (all covered with hardware cloth.) And the pop-door has never had a door. Additionally I have venting under the eaves. I've got to close this up, they probably aren't on the roost in the coop because of the draft from the big east west windows, which I am about to cover. Question - should I cover the north-south windows under the eaves as well, and the pop door that faces north? I can put a hanging flap over it of pond liner. HELP!!!!
