All chickens will come and peck at the new kid on the block. Usually it's the hens establishing their pecking order. As said previously, a "see-no-touch" barrier in their coop for awhile will help. This may take more than a week or two.
I had a serama pullet that was having a particularly difficult time with my other two seramas hens. My kids had some tv time with the little ones in their laps next to each other. There was some occasional pecking, but the kids were able to keep it in check. It seemed to help.
