It'll be about 5'4" tall at that side and I want to put vents on that wall so how far above where the roosts will be should the vents be? This will be for winter so they won't be blocked. For winter vents, do I just need to make sure vents are high up (the coop will be about 6'2 on one side and 5'4 on the other) and for summer use closeable windows down lower? At what temperature do I stop wanting a vent at the lower level to be open? I'd love to see pictures of your coop ventilation. I want to do this right the first time because I don't think dh will want to do any modifications once we get finished.
