I have eight Chickens in my flock including 2 roosters and 6 hens. The 4 Ayem Cemani's all get along great, even though 2 of them are roosters. However when I introduced 4 other chickens which I have had for over 5 years, one for 7 years. The older ones all huddle together in a corner. The odd thing is that none of the Cemani's have tried to hurt them. The Roosters have tried to dominate them, but not in an agressive way. I am concerned the older Chickens my starve themselves if they dont integrate with the group. I want to keep them all in one coop if poss, any suggestions welcome ?.
