We built this 12 x 16 foot coop from scratch. It has 3 x 12 feed storage area and the remaining 13 x 12 area is separated by removable panels. We built sandwiched hardware cloth between 1 x 2s so there wouldn't be any sharp corners exposed. The perches are 1x3 to give them a comfy roost. We kept the EE and guineas separate until they got use to each other then we took the panel out so they have the run of the entire coop. The guineas tend to bully the EE but they are rarely in the coop at the same time except at night.
