I have a lot of ventilation in my coop and barn. Between the boards and big vents at the top with 1/4 in wire over it. Then in the summer I open the chicken door and cover it for the summer and they just go in and out of the big door. I only close the big door at night and the chicken door stays open but covered. Some times I put in a fan or two. We also have a covered run. I put bottles in the Ice box and take them out there when it's real hot.
The barn covers the coop in the afternoon from the sun in the summer and the wind and rain in the winter. The runn is covered also. Works well. Good luck
