There are any number of euphemisms in the English language for the actions of roosters. The two that come to mind right now are 'the cock of the walk' and 'to rule the roost.'
They both have the same connotations meaning in the poultry world the male is dominant. Mature roosters will generally not attack a hen because he doesn't need to attack her to establish dominance. The universal exception to this rule is if the hen shows aggression, especially to a young rooster. It can be anything that a new chicken person may not notice like her spreading her hackle feathers, a peck, a look, or a hen's refusal to give her favors to the rooster. Also right up there are two hens fighting. Rooster can not stand that and will break it up quickly, more likely than not siding with the under dog if there is one.
The only exception I have seen is a blind or near blind rooster put into a strange pen or coop hitting at his hens every time one comes close to him. In the pen the rooster came from he was dominant (in his mind) and he intends to maintain his dominant in the new pen. Finally all chickens dislike weakness. If a member of the flock should have something suddenly happen to them where they display weakness (say a heart attack or other sudden onset of illness) every rooster in the state (and half the hens too) will jump on the down bird especially if it was a dominant bird before the sudden event occurred.
