This is the semi final coop after 3-4 revisions to keep adding footage. We started out with a 4x4 foot inside and a 4x10 foot run underneath. Then I added on another 4x4, 2 story area with the wooden door. That then became a duplex with the big girls on top and babies on the bottom. Eventually it will be one big area once I migrate all the girls together. I then added on another 4x6 foot run for the infants. The big Girls free range an hour or so a day. In October they will all mix and The coop will be one big mansion. Enjoy!
