I'm building my first coop. It is a 4'8"Wx8' L with 4'H walls. I have a full ridge vent, vents under both gables ,2 small vents/windows above nest boxes on 1 side of coop & a 22x 42 window on other side. I'm getting ready to close in the eves should I install some vents there also? In winter do you close some of them. Thanks for any advice you can give. WAC
