A good rule of thumb is 4 sf per full sized chicken in the coop and 10 sf per bird in the run. Using that figures to be 4 or 5 chickens. I remember mentioning that in the first response. Raising chickens for 30 yrs now I have used many different coops and set ups. You will figure it out and what works best for you and your hens. I like having healthy birds that have never been in "jail" or that are "crammed" so no need to think I would ever recommend that.
Wish ya the best.
