Ok, I have read so much on the topic of ventilation I want to know if I have this right. I plan to put some at the bottom of the coop, and 4 inches of space under the eves of the roof. I also plan on putting windows that I can open and close whenever needed. I live in the Seattle area, so it doesn't get super cold, just wet, so my coop is raised. Do I need to be able to close the area under the eves if it's protected? The 2X4 roosts will be in the middle area. Any thoughts? The house is 6'X4', 4' 6" tall.
