The shed we're getting has no ventilation, so far as I know. It is a big shed, 12x10x10' high approx... It sounds like the easiest/cheapest way to add ventilation would be to cut holes up near the roof, frame them off and add chicken wire attached to the inside? Is that right? How big should the ventilation areas be for a shed this size? Do I need the ventilation areas to have a cover in the winter months, or should they remain fully open year round? The coop is not insulated, and it can get pretty cold up here, especially at night. What about snow and rain blowing in through the wire openings? The roof peaks would be facing north and south, with the south side 6-10' or so from our tree line. As for windows, what should I be looking for? And does it matter which way they are facing? I was thinking 2 windows on the south side, 1 each on east and west. Probably not any on the north side, since the door takes a lot of space. Plus there will be a divider blocking off the front 4' anyway. Here's the shed. I'm not sure what the long skinny thing on the roof there is? Is that some sort of vent, or what might it be?
