After a night of rain & mild temperatures where winds shifted from southwest to northeast (meaning I could not leave any windows open), I realize I need to stop merely thinking about this & take some action for keeping my coop dry & not have humidity build up. Ventilation with a sealed motor that won't overheat due to dust is what I need! Just add an automatic thermostat & build a nice hardware cloth cover to keep determined mice out.
