For your edification, sure. This photo is a probably 6 months old, and things are always changing here, but it will do.
The fenced area is a total of about 8K square ft, separated into Stilton's area (9 nesting boxes in 2 coops), Merle's (3 nesting boxes), Andre's, and movable communal foraging area. They spend the majority of their time in their area even when access is open to others.
Communal foraging area is sometimes the better part of 1,000 acres of undeveloped land around us, but I've never seen them orbit more than 1/2 acre. They know better than we do how many predators are here.
If all humans leave the property >1 hour (which happens <8 hours of daylight/week), chickens are closed into their runs, where they often spend afternoons by choice anyway. For Stilton's crew, that's 16 sq ft/chicken, 24 sq ft/chicken for Merle's group.

Wish we could give them range without confinement, but we have an exceptional amount of predators. It's common to look out and see bears, coyotes, bobcats, foxes, raccoons, etc. wandering by. Also common for neighbors to have total losses to attacks.
Some buy new chickens several times a year. Others never have chickens again. Neither approach sits well with us, so this is what we came up with.
