We are in the process of building our very first coop!!! We live in St. Louis, MO. It gets VERY hot and humid here in the summer (ugh) and we want to make sure our girls have enough ventilation. Here is an example of the coop that we are building.....so far we have the frame work stained and the area leveled. COOP EXAMPLE OF WHAT WE WANT Our coop will be about 2 feet from our privacy fence on the back wall of the long side. We will add the smaller squares like in the photos for ventilation and a larger window that opens on the outside coop door. Should we also add another window on the left side of the coop above the nest boxes? All of the windows will be able to shut. Do people add fans inside their coops as well? The entire top of the coop is open air w/ hardware cloth as well and we will add plywood in winter to cover that up. Our coop will also be a reverse of this design w/ the house on the left since there is more shade there in our yard. Thanks for any help!
