I have seen some great coops with ventilation at the top or near the top and have already created that for my new coop. I have not however seen (or perhaps never noticed) the lower ventilation recommended for trying to keep the coop cooler on those hot summer days. I do have three windows (2 small and 1 large) that create a cross breeze and obviously there is the chicken door itself however I have not planned any other lower ventilation. Recommendations? Pictures of examples? Tks.
