I have 19 chickens,: 2 roosters and 17 hens and a large coop, and let them free range most days. i would like to build a second coop and start another flock from day old chicks as i did the first group. what do i avoid? will they all get along eventually, does it matter? will they avoid each other ( which is fine) , ? the coops will be 100 ft apart or more, but they will be free ranging in same area. chickens are AWESOME !
