I have 7 chickens , 8 mo , 7 mo and the youngest 2 are 6 months old . The younger 2 have been kept in a small coop from tractor supply beside the larger coop we built which is 12x 4 ft . It is supposed to hold 8 chickens . We would like to put all 7 in the large coop which has an automatic door but we’re wondering if they would peck on each other . All the chickens free range during the day together . I didn’t know if it was a good idea to put all 7 together
