All comments welcome..... 10x20 shed is elevated on piers 8 inches off ground with welded 1x1 wire from bottom of shed to ground all the way around. I will wall of back 10x10 for coop, install man door from front half of shed to coop, one window facing south, self powered roof vent, a couple 8 inch screened floor vents i can close if need be, and insulate everything including floor. I guess i'm going to try the deep litter method on top of linolium floor. Pop door will be center rear of shed with walk board and sliding on bearings and metal drawer slides with a safety lock. 4-boxes on right side 24" off ground, ladder type perch up left side all the way to top with big poop board underneath. Ladder will be hinged at top so i can tilt it up and slide out poop board Run comes off rear of shed and goes left and right of back half of shed and will be privacy fenced on both sides and 8' wire across the back and on top with hardware cloth on coop side of wire. 12 large hens, 1 rooster, 100 sq.ft. coop, 550 sq.ft. run. (Keep in mind that I know the run is big enough normally.....but I will not be able to free range much at all outside of run. I've researched quite a bit over the last year, but probably missed something. Please chime in with anything you would do differently and why. Thanks so much everyone.
