Hello Everyone, I know there a ton of posts right now regarding cold weather-proofing our coops, and I will read each and every one of them this evening I have a couple of hours today to work on the coop, so I'm hoping to spend as little time as possible reading long posts. Our coop is 4x8, has a standard pitched roof, with the higher portion in the south side. Here is a pic: The rafters are completely open, and hardware clothed in. I am hoping to batten up the rafters for the cold nights and any lingering cold days. But, I'm not sure how to go about doing this. Should I focus on closing up the southern higher rafters, or the lower northern side? The girls perch runs along in front of the window in the coop. Perhaps I should close up both the north and south side rafters, and leave the coop vented on the door half of the coop? I guess what's confusing me is, I'm not sure about the air movement within the coop, and how to provide the ventilation at the top, without letting all the internal heat out. Here are some more pics, specific to the rafter situation: Exterior South High Side: Facing West Perch/Nestbox side of Coop: Interior South High Side: Interior North Low side: Facing East - Doors/window/run Side: I'm also gonna need to do some insulating. I think the roof is going to be kinda tricky, because of my ventilated rafters, so any suggestion on this would be greatly appreciated. From my understanding, I could lose alot of heat through the roof, but if I insulate the walls, will it still be so important to insulate the roof? Also, must I insulate ALL the walls, or could I leave a couple open? If this was an option, are there any walls that would be more critical? Seriously, I do plan on doing my homework off other posts, but I am just hoping to get sosme specifics regarding the setup of my specific coop. Thankyou so much!!!
