Hello folks, Hoping some of you can give me some ideas. I plan to build a shed in the spring. It will be 12'x20' about half will be dedicated to my rabbits the rest will be divided off for poultry. I live in Northeast Missouri. We have several weeks of near 100 weather every summer and in winter we have a few days close to -20. So i am looking for ideas to provide a lot of ventilation in the summer without freezing them in the winter. Shed will probably be post and beam construction with steel siding. If it was wood siding i would just cut a couple of large windows and build a door to swing up in cold weather. Not sure how to do that with a steel siding. Any ideas? Any pictures of a similar setup would be very welcome.
