The drawings are awesome. It makes me feel better about our ventilation. We have a shed roof on ours with vents on the low side facing north which is shady with trees, the high area is to the south. We have soffit vents on the south side and also top hinged windows. This is where our mostly covered run is. We also have hanging fans in front of the north facing vents to pull the cooler air on and upwards through the exit vents. When we had 105 days this summer with no wind it was very hard for the chickens but we helped mitigate this in different ways and everyone survived, I do know there were people here in NE who lost many.
