I looked on BYC for a long time for a coop design that I wanted and didn't quite find exactly what I was looking for.
The Palace here at G&B farms; home of The Fabulous Chicks is 12x24 7 windows, 1 door, 3 inside/outside pens, A Frame roof, hallway, with T1-11 siding that will be painted barn red.
Each run is 8x24x6' Each run has a gate for access, hardware cloth dug down in a 12" ditch to deter predators. Each pop door has a ramp we covered with shingle's to keep them from slipping. This house only houses Purebred birds: Welsummer's, Australorp's, BRLWs and Ameraucana's (3 EE's) but we always know their eggs!
Finished outside pens 3 separated by breed
Welsummer's on left, Australorp center, BRLW/Ameraucana's on right.
