Only time will tell.
I can tell you tho that having multiple cockerels brings out all their worst behaviors due to the competition.
Young cockerels will almost always try to mount pullets before the pullets are ready,
just how aggressively they do so is an individual thing.
Knowing more about your chickens would help,
-your flock size(numbers, ages, genders).
-your coop(size in feet by feet with pics).
Multiple males are problem, get rid of all, or all but one.
