I saw some great coop design with some nice ventilation ideas on this forum but am unable to locate them now. It was a rectangular hole with grills on each side of the coop for cross ventilation. I am having someone build me a coop but his current design has little to no ventilation. The person that is building it is remote and I'd like to send him some photos so he can modify the design to include more ventilation. Can someone please post pictures of the ventilation part of their coop so I can get some ideas? Thank you much.
