I'm working on my coop (you can see the progress in my signature) My chickens will have limited free ranging because of neighborhood dogs. I won't leave them unattended. Anyway, I plan on having 10 chickens. (well with the way chicken math is going.. 12 chickens) The measurements of the run are 17ft x 15ft Is this adequate for 10 (or 12) chickens? The coop is 8x6. They'll be allowed into their run every day, but not outside the run unless I'm with them.
