Your pig set up sounds good, porkpal.
Dave, I was thinking pens on all four sides of the coop but maybe as big as your pens are going to be (40 x 50, weren't they?) you may do fine with dividing what you have planned. This may save some construction money also, especially since part of the reason of having divided pens is for when you introduce new chicks which, being smaller, won't require the same square footage as the laying hens will. Maybe the same for the meat birds also since they'll be small to begin with and then over and done with in a couple months.
I remember how fast my birds would defoliate my pens but perhaps i had too much activity going on. I can't remember the recommended square footage in a coop for the various breeds (heavies vs moderate or light weights) nor the recommended square footage for grazing pens but that should also come into play when considering the number of chickens, as I'm sure you already know.
I once had a coop I could place in a garden/field and would run temporary fencing off various sides using fiberglass electric fence posts with fabric fencing (nope, didn't use any electric wire). I could easily set it up in a given run in my garden for a period of time then pull up the posts and put them back in on another side of the coop in another area of the garden. This wasn't as time-consuming as moving a chicken tractor every couple of days. Since your property is hard fenced keeping 4-legged predators out it could be something to consider. Personally, I like your idea of a solid coop and no moving of any fencing (or chicken tractor)!
Back to fencing around your coop, can you place the coop where you can add an extra pen off the fourth side later if needed?
