8x12 run containing 8x4 coop (4' in back, 5' in front), intended for a flock of 3 Orpingtons, with potential for roo and chicks. Should technically be able to house 8 chickens. Hardware cloth on bottom two feet and windows, 2x4 welded wire above that (assuming it is cheaper.), possibly strung fishing wire for run "roof" until a real roof is necessary. A and B are alternative backs. I have a bifold door in my garage (each panel is 15 inches wide for a total width of 2 1/2', 6'7" long), and am considering using it for the back with hooks and eyes to support the lower panel during clean out. I'm not sure if it'd be too unwieldy, or if it'd be adequate space for clean out. Another problem with that is that it prevents using a 4x4 for rear center of the coop. I'd appreciate comments, criticism and advice.
