Hi all! My husband finally finished our coop, and it is gorgeous! I have asked him to put cross ventilation in it several times, but he was on a mission and did not. There is a lift down window that runs the long length of the top of the coop, if you open it it is covered with hardware cloth. I am concerned it's not enough ventilation! My girls are 9 weeks old and we were going to move them in tonight, but its pouring rain and dropping to 45 overnight so I am going to keep them in the garage another night I think.
