I've already got the maximum amout for my chickens 11. I think I should get nine, ten, or eleven. My mom says eight. I heard that more is better. Is that right? Please tell me if I should have 8 9 10 or 11. COOP 6X8 RUN 13X11 (bUT AGAIN SOMEONE TOLD ME THE LIMIT.) I already got 4 chickens in the coop.
