We have three different groups and are about to add a fourth to our flock. They definately stay within their own group by time of hatch at our house but they get along. When you go into the coop at night to close up they are all on separate roosts according to group.
My original 5 girls are definately interested in the babies. I figured it was more about getting to their food than the chicks. Now four of them are in the coop and we're about to let them loose. There seems to be no squabling. I'm guessing they worked it out already. We let them all out together for a little while this weekend to observe and it seems all is ok within the flock. We're talking two months though that they've seen each other through the fencing.
Give them plenty of time to get used to each other is my experience.
