If you plan for 12 long term, and zoning permits it, and you have space to set aside for it, recommend you stake out a square 12x12 for combined run and coop to give yourself an idea of how much space you should be contemplating as a minimum (144 sq ft as an "open air" coop design). If you want a more traditional "shed-like" coop with attached run, you should be thinking more like 10'or12' by 16' or more.
