Ah, yeah, both of those would be less docile than Salmon Faverolles in general. Since you say it's only a couple of them, you can try temporarily removing the bullies from the flock. If they have to reestablish themselves in the pecking order they may be too busy to bother the cockerel.
Edited...
What breeds are your hens? Salmon Faverolles can be bullied by other breeds because of how docile they are. Also, he's a bit young to be leading a flock anyway. Give him some time to mature and he might do a better job.
