Okay I am having the chicken crave. I have 6 right now. My coop interior is 5 1/2 feet by 6 feet with two roost going along the length and width of the coop. I have a run that is 6 by 16ft( they can go under the coop). I've added a little chick door since this photo, and added a small uncovered fenced in area. Most evening my hens get free range time. My question is I want two more ameracauna and two olive eggers. What do you think? That would mean 10 chickens for 33 sq ft. so 3 sq ft per chicken for the interior of the coop, not including the run and extra fenced in part for the day time.
