Your cockerels are starting to mature, but are at that 'idiot adolescent' phase right now. Your hens (and they are all over one year of age?) are not impressed.
Since these are your first cockerels, it's possible to miss early evidence of human aggressive behaviors, a separate but very important issue. Sometimes it seems to me that new owners don't see any problem until the bird actually attacks and causes an injury. Hope that's not going to be your experience!
How many hens do you have? If the dominant cockerel is causing injuries, or really being obnoxious to the hens, eliminate him, and see how the other bird develops. You might have a nice bird there, or another looser, and it just can take time to decide.
