I am not so good at math and need some assistance.

I am figuring to have about 16 laying hens and am trying to design my coop with that number. I will have standard size ladies(BA, EE, FBCM, and Red Star), from what I have read I need approx 2 square feet of space per hen. I have been working on this all day and I do believe my brain is tired...can you give some examples of inside "footprints" that would achieve this? like a square of such and such or rectangle of such and such. any help would be greatly appreciated.

 

Thank you, Thank you ---I can build the coop as large as need be, I am working with approx 1 acre of lawn space( I will also have a chicken tractor for mowing the grass ) I am undecided on free ranging--too far a distance with no fencing, I would hate to lose the ladies...I will have to give it test runs perhaps. So the run can be as large as I wish to build it. I have most my ideas planned out as far as materials to use, but obviously not how much of it since I couldn't figure the specs out. I even scrounged an old shower door for a sky light(passive heat source in winter) and ventilation( hardware cloth underneath with a locking mechanism to "prop" the door open in summer). Thanks again for the help, it is much appreciated.
