I don't think my coop is ventilated well enough to remove moisture as I had a mild frostbite issue during the recent cold snap. Admittedly, it was -10 with wind chills closer to -20 but I'd like some opinions on what I've got versus a modification I'm considering. You can see the outside of my coop in the first picture below. It is loosely based on the Wichita Cabin Coop type of design with the coop/run as a single structure. The door to the run is hardware cloth so there is some air flow into the run. The second picture was taken from inside the run facing the coop. For reference, the door to the run in this picture would be behind me. You can see the ventilation I have at the top of the coop that leads into the run. I do not have any additional ventilation in the coop. So, my question is should I add some at the same level on the opposite wall in the coop. Will this be sufficient for it to work properly? The roosting bar is below the level of the ventilation. Thoughts?
