I finally finished building the coop/run annex! I am quite pleased as I built the whole darn thing all by myself. I still have lots of painting to do, but the thing is up and the chickens have moved in. The new run is 16'x20'. The left playhouse is the roost hut and the right playhouse is the nest box house. The shed/lean-to in between them is 4'x8' and about 3-ish feet tall. The playhouse are the Lowe's playhouse kit with some modifications. The top of the whole thing is covered with netting to help deal with random hawks. I zip tied it together and to the chicken wire.
