I would agree that every rooster is an individual, but in my opinion the little ones tent to be more aggressive but then Ive only had silkies as bantams, I have A huge Orpington Roo Also ( he came from a breeder that bred them very well to be gentle), that loves everyone, kids included, but he was raised from a tiny chick with the kids coming over everyday to feed treats and such . The meanest Rooster ever was a silkie Roo named Flame and he hated everybody! and would chase people down to attack He was a jerk and didn't stay here long! But like it was mentioned before, there are no guarentees to get a nice Rooster your best bet is to go with a breeder that breeds for temperment as well Quality. Sandy
