Is the ventilation up top the only ventilation you plan on having? Perhaps leave the front top half open covered with hwc and make an awning so the rain doesn't get in but you have lots of airflow... You're making great progress!Had a few extra pieces of OSB and salvaged off of a bunch of pallets. Got two more walls done. One more wall and I can add electrical. She’s getting a fan, lights, and a big zapper!!! After that is done, I’ll be running water to it and modifying my waterers to accept a hose for auto fill and also adding a spout so I can add rooster booster to them periodically. I’ll also be cementing the floor so I can start putting bedding in there to make for easier cleanup and adding some roosting boxes.
