I need more ventilation. I built it to keep drafts off the roosts in winter, and it is insulated, but that means even with the East and West Windows open no breeze goes to the roost. I need a Summer vent that I can close up later.
There's a hydraulic vent arm that requires no electricity or batteries it operates on temperature pushing the ram open with heat and closed when cooler. I've built a metal chimney with the vent on top to open and close. Idea of chimney is when it gets hot from the sun then it draws hot air out of coop. That and the vent and fan in the door works really well.
