I am almost done building a 12x20 coop that has a dirt floor and wire apron around the base. I believe It cost me about $850-$900 for everything. I have bought everything to complete it I just cant find enough time to finish it. It is built like a pole barn and has Rolled Roofing. Still needs to be painted though. I don't have an updated picture but It has wire on the rafters on the outside to keep coons out and a 2x6 running on the front side of the rafters. I will ad more windows this spring I couldn't find any cheap one for sale on craigslist. This will house my free range RSL Flock of about 60 hens.
