When I get new chickens, I put their coop inside my run so they are in there with the existing ones, letting them get used to each other. When I do let them in the big run, I put multiple feeding/water stations, and lean pieces of plywood on the sides of the run in case they need a place to hide. The first time I introduced new birds, I had 6 hens and a rooster, and introduced 6 new birds. It was horrifying with the bullying. This time, I introduced 8 new birds to the 12 (one passed suddenly) and there is occasional pecking, but no bullying. The more stations you put out reduces the amount of resource guarding, as they cannot possibly be everywhere at once. My newbies go into the coop at night to roost, but don't really go in there during the day just yet.
