We have a 10ft by 16ft gable roof storage barn. We are making the back 8ft by 10ft area into a coop. I have everything figured out thanks to all of the advice and information posted here except how to securely, easily and inexpensively screen in the back 8ft from the front 8ft. Do we screen all the way up to the roof? Do we screen under the rafters? In the pictures I am taking down the plywood loft to improve ventilation.
