Newbie in the throes of planning a hen house here.... I think I'm going to keep it simple with an 8x8 house with a 'lean-to' roof. Here's my question: on the triangular sections between the top of two walls and the roof I am considering leaving those open and covering securely with hwc/chicken wire for ventilation. However, I am torn between planning for enough ventilation and making it too drafty for my girls (at present 11 three-week-old chicks; I may in the future increase flock to a total of 15 hens). I am also concerned with heat in the winter. At first my coop won't be insulated (2x4 framing with siding); planning on keeping a close eye on temps inside the coop as winter comes on and acting accordingly. No power to the coop, so that rules out space heaters, lightbulbs, etc. It can get down to several degrees below zero F here. Another big concern of mine that especially relates to drafts and heat retention is that we get some wicked winds. I am planning 3 or 4 roughly 24"x18" windows (the hwc and plexiglass sliders seen on this forum). Should I come up with a way to cover those triangular sections in cold weather? I am wary of closing the coop up too tightly in an effort to avoid the cold and drafts and then having a problem with not enough ventilation. FTR, the section on the front of the coop where the lean-to roof is at its highest I also plan on securing with chicken wire, but that is a larger section and I'm already planning on some kind of cover for cold weather, but allowing it to be open during summer. Ideas, suggestions, guidance?
