This was built this weekend to replace my 8 year old coop. Love the exterior access to the nesting boxes. Built in human door with a chicken door as well. This was built with mostly palletts. Not planning on painting it, will add a couple windows in a few weeks. The run does appear small, but my chickens are usually free range with the option of the enclosure. Right now I am limiting their trips outdoors while they get used to the new coop, and while i introduce some younger chickens to the flock.
