I ususally let my new starts get nearly mature before I introduce them to the flock. I just put them into the coop and then keep them fenced in for about 2 or 3 weeks. By then they are accepted into the pecking order, and I can let them free range again and they can find their house. This fall I had just one to introduce to the flock, and I was worried that they would really pick on her as she was the only one. I snuck her in during the night and put her on the roost. It was ammazing how thay accepted her.
