We'll be putting up our coop/run in the next few weeks and I'm really in need of some visuals. I know ventilation is very important, however, I don't understand drafty versus well-ventilated. I'm a visual person and can't seem to find any images of what to do and to avoid,if that makes sense. I'm in North Central Texas (so, it gets really hot and into the teens as well). I want my ladies to have the best, manual, ventilation we can design.
