I used these plans to make a coop/run 8 years ago. Because I used nearly all plywood it needs rebuilt now. There is a pic of the backside of the coop on my page. I replaced the 1x6s in the plan with 2 pieces of 3/8"s plywood glued together.Which is why it needs to be rebuilt now. I also used 3/8's in plywood in place of the 1/4" which the plan called for. I'm posting these plans for others who may wish to try this for a run or coop.
