Nice build. Love the color also. Any holes you have for ventilation, cover with 1/2 inch hardware cloth and secure with screws and washers.Thank you! The high side of the coop faces almost due south. As I've built it going into winter, I didn't add ventilation ports. I foamed the underside of the roof on the south and west sides leaving the east and north edges of the roof/wall junction open. There is roughly a 1'' gap on the east and north sides at the top of the wall for the entire 8' of each wall. The doors on the south and west sides have a small 1/8" or so gap around them and for now, the chicken access door at the base of the south door is open for 15+ hours a day. If that still isn't sufficient come next summer I can easily cut and add grilles at the top of the south and west walls. I am new at this so please do comment if I've erred in my approach.
*edit* to add that prevailing winds, even during storms, are from the west-southwest.
