I have a lsmall flock of 10 hens (Silver Laced Wyandottes, Black Australorps, Ameraucanas, White Rocks) that turned 1 year old last week. They spend half the day in the coop & a few hours free ranging in my fenced yard. They return to roost and I lock the door after dark. I received 6, 3-month-old pullets over the weekend that are being housed in a separate coop (Rhode Is. Reds, Ameraucana, Barred Rocks). I eventually want to house them all together. What's the best method to get the older gals to accept the younger ones once I allow the young ones to free range? I'd also like to house them all in one coop, where the older ones & the automatic, (deer) feeder are. A friend told me to put new ones in the coop at night & in the morning when they awaken, they'll all get along. That has not been my experience over the past 15 years. I have just been keeping 2 groups separated & when the older ones' egg production slows down, they go to friends who will process & stew them, then the younger ones move up into the bigger coop.
