O.K, so, after reading about adequate ventilation, I've decided I need to add more to my coop. I have insulated the coop for our canadian winters and I don't want that to be in vain. So, if I cut a large , triangular vent at the top of my coop, just under the gable peak,( to match the shape of the peak) can I put a wind guard over it, about 2'' out from the coop? The guard would be enclosed around the edges except for the bottom lenght.( which will be 24") would that work to still ventilate the coop, or would the guard cuase too much interference?
