Our new 8X20 coop and run, almost finished, except for some paint, trim, and a ramp.The coop windows are hand made from 2x stock and some left over polycarbonate material from an old tear down years ago. The coop doors also open up like the windows, so my pulley system works for both. When cleaning the coop, we just move the fastener from the window down to the door and hoist away. The vent openings above are covered with hardware cloth on the inside. Still haven't figured what we want to place outside yet.
