Some will, but most will not.
A lot depends of the genetics. He may go through a showing off stage when his hormones kick in. I have many roosters and NON are aggressive at all to humans. In fact they are actually easier to pick up and handle than most of my hens as they are less afraid.
However, I have some 5 week old chicks and one of the young roos in there is going to be a problem I think. Even as a very young chick we will peck and bite my fingers when I try to pick him up. All the other ones just act normally. Its strange as he is the very smallest and lightest one, and he was sick and runty when first hatched (I thought he would die).
None of my chicks are mean to me. But I do have one that I have already identified as a definete roo...he pecks the other chickens when they get excited and run or fly getting their "yammies" out. Unfortunatly for him he will be first in line come harvest day.
