I've integrated my chicks with he older ones. The best way is to put them out at night when they are all sleeping. I did this and they did not fight each other. The smaller chicks have been grouping separate from the others, but have also been mingling with the older ones. My coop is bigger than yours and has more chickens. So the large area allows them to get used to each other and get familiar. I previous years I've introduced new chickens at night and the fighting has not been there. Then they eventually grow into a unified flock. The only times I've had issues has been introducing during the waking hours.
