Well then .... maybe this will help. I recently wrote an article on integrating groups. Since they all hang out together in the yard, you may not need it. But here it is anyway. It's just a 5-minute read, with lots of pictures.During the day all my chickens are in yard together. At night I have 2 separate coops, one for my big girls, and another one for everybody else. The big girls were my first chicks, and as I added on, I was like “I can’t put the babies with the bigger girls” so now I have two coops. I’d love to have everyone in one big coop.
