I am still mulling a coop design that will be built possiably this fall, maybe this spring. I plan to build this once and build it right. I do a lot of cabinet & carpentry work so that is not an issue. Some of my questions are around ventilation right now. How much and how little is the thing I ponder now. A plastic ridge vent would help get some hot air out in the summer, but there is no easy to shut it for the winter, do I need to allow some air movement in the winter here in NE Connecticut or should I plan to shut it up tight? I would like to not heat the coop in the winter so it will get some insulation in the walls, but without a ridge vent I do not want to insulate the roof. From what I understand this should be fine as some do not even insulate or heat. I am planning on Barred Rocks and RI Reds so far. (still in the planning stages) Can I get away with just two small open windows (caged) in the summer even if they are on the same wall? Or would I need to re-think this and add cross venting?
