I've searched on the ventilation threads, and haven't seen this question answered. All of the ventilation pictures with flaps, etc., I've found are for non-insulated coops in warmer climates. How do you build ventilation flaps into insulated walls? I hope I can explain myself properly: we are building an 8 x 10 coop, framing the walls with 2 x 4s and using OSB on the inside walls and T111 siding on the outside walls, with insulation batts sandwiched between. In addition to a few windows, I am planning on cutting long ventilation flaps in the exterior siding running the length of each of the 10 foot walls (6 inches tall, at the very top of each wall, up under the eaves), as well as on each of the 8 foot walls. These will be hinged so I can lower/close them. When framing the walls, what do I need to do to keep the insulation inside the wall from getting wet when the ventilation flaps are open? Has anyone built an insulated coop with this sort of ventilation? Should I nail a board horizontally between the framing studs at the top of the insulation level - sort of like a mini header? I'm not sure what else would work - does anyone have any suggestions? Any pictures of insulated & ventilated coops would be very much appreciated! thanks, everyone!
