Hello! So I am going into my first winter with chickens. We have had our first cold spell and good snow here in Kansas City, MO and I have some ventilation concerns and am in need of advice. So first let me say that this coop is the first thing I have ever built besides a flower box in high school. It is 6’x8’ and about 6’ tall. I have a mixed flock of 8. Earlier this week I noticed one of them has a little frostbite on her comb. She is a Rhode Island Red. It’s not super bad by any means but still a concern. That night it was in the teens. Our climate here is very up and down. We typically will have a week or two in low single digits dropping below zero at night once or twice a winter as well as a nice weeks in the 50s and 60s. We sit at about 60% humidity as well. We get snow just not constantly. Every few years we get dumped on with a good 8-12” at once and other years maybe 5” total.
So the coop sits on the ground on concrete blocks with 2x6 floor joist and a plywood floor covered with vinyl. It is modeled after the coop from the show fixer upper it you know what I’m talking about. The extirior walls are 2x4 framing on close to 16” centers. They are covered in the cheapest plywood I could find which I regret. Then I have cedar shakes nailed in to that as siding. I did cover the plywood with a moister blocker before the shakes went on. I have 2 windows opposite of each other that I made myself out of glass panes and tongue and groove pieces that are siliconed together with some added support in the back. One is 8x10” I think and the other is around 24x36”. They are attached by henges at the top. The small one faces northwest and the big one southeast. I also have a long vent that runs the 6’ side of the coop over the nest boxes. It is 2-3” wide and isn’t covered very much. Last night I cut a new vent under the roost on the northeast side. It is 15” wide x 5 1/2” tall. I am going to put a cover on it soon to block any wide that could blow in. I also cut a section out of the plywood under the roof between 2 rafters in the peak. It is about 15” wide and 5” tall on each side. The ridge cap covers it so there is only about a half inch gap at most between the ridge cap and the metal of the roof but it does span the 6’ that ridge cap runs but 5ish feet of that is covered by plywood on the inside. As far as drafts the coop is not too bad. Air does leak through the window trip but I plan to caulk around that. Then possibly get some sort of weather stripping for when I close the windows. The big vent above the nest boxes does cause a draft but it is pretty high up. The new vents also have a draft but the lower one I have a solution to and the roof shouldn’t be an issue at the roost. Other than that nothing to big as far as major air movement in there.
So my question is do I need to add more vents. I could add more by the roost on the northeast side. Could be top or bottom of that wall but if it’s on top then it would be level with the roost. I could also cut the plywood under the ridge cap along the whole peak but I’m not sure if that will actually give more ventilation. Any help or advice would be great!
