So I live in a 300 year old home and when we bought the house there was an old post and beam shed in the yard that was slowly rotting from bottom up. After 6 years- and many other projects- I finally tackled it and made it into my chicken coop. We have had chickens for years, but a smaller coop. Half way through. You can see where I had to replace the lower parts of the old 8x8 and 5x5 beams that were rotted along the bottom. Now. Front door made from old shed wood. When you open the door and walk in, the coops are to the right, one for the standards and one for the bantams. There is a small hay loft on the top for hay for the donkey and goats. The nesting boxes are built to open to so that I dont have to walk in the coop itself. The back folds down. Inside standard side. I built pop doors that lift and close from a rope that goes outside the coop and into the shed. I just pull on it to pull it up. No pulley system, just climbing ropes and I hooks. The bantam side. Matching, but smaller nest box. Inside of bantam side. Again, a bit smaller. Happier customer, at least they better be. Dug approves also.
