We are turning an existing garden shed into a "duck house" Existing Shed: Facing the shed; the run will be on the right. I am very interested in your ideas about cutting out vents and doors. I am sure I want a "pop" door on the right side, so any ideas would be great. But what I am most interested in is the vents. As you see I can not go high on the sides, I can put some in on the front and back. I see where people have cut out the wall and reused it to close it back up when needed. What are the rules of thumb for doing that? We do have 2 small windows with screens that we will be installing; one on the Left side - as high as we can get it, and one on the back wall. With a Pop door on the right, how much more openings will we need for a good cross breeze and for proper ventilation? I have ideas but would love all of your input we are getting close to cutting time and I want to make sure we do it right, the first time. Thanks all!
