Thank you! We do have orphingtons!this coop will hold 6 hens or 5 and a rooster. with large breeds like orpingtons you may want to build it larger on the run area. of course this would mess up the directions, but if you made it 6 feet wide and 12 feet long, leaving the flower box off it would work pretty well for you. you could also build it as is and add another 4x8 run beside of it before you put the wire on.
