I need some sage advice I have an 8 x 8 shed that I'm converting to a coop. Peaked roof. It has two fold down 'bunk beds' attached to the back wall. They're made of plywood. They fold up and latch to the wall if unneeded, or lay horizontally and are about 3x8. I'm guessing the previous owners kids slept out here on summer nights. The bottom bunk is low, and only sits about 18" off the floor. Once I've put bedding down, I think I should leave it up so that I don't have chickens squeezing under there and laying eggs. However, I'm wondering if I can build their roost above the top shelf/bunk and have a very handy poop scoop tray!!!? My worry/issue is ventilation and drafts. If I open the windows, the air will be coming in between the roost and the drop pan. In the summer would this be a problem? In the winter, I'd have those windows shut but the roof (with vents installed) would only be about 18" above their heads. Is that too close? Seems that it may be a draft issue. I can of course put in a lower roost and just hook the bunkbeds up to the walls, but it seems like it might be nice to use it and give them a little more clean floor space under the bunk. The other, much more labor intensive option is to remove the bottom bunk and move it up a foot or so. I still think the windows in the summer would blow on them, though. Help! I can take pics if needed, hope I explained that well!
