My cockerels are 14 weeks, still not mean. I am not keeping the breed because I only have so many breeding pens and had a large cockerel to pullet ratio with mine, so sold the pullets and am waiting for the boys to get a bit bigger before I take them to the swap. It may be that they are the youngest and smallest in my rooster coop that keeps them calm.
If you have a dominant rooster in your flock already, I would let them grow up with him. That is all that kept mine in line at all. He had to give them a lot of attitude correction. The pullets are docile, but those roosters...None of mine attacked me personally, but they do not play well with others unless they are well aware of their place in the flock from the beginning. Even then they will attack other chickens if they think they can get away with it. I just got rid of the last 2 cockerels and will let the remaining pullet free range here. She sleeps high in the trees and is pretty uncatchable. No more QS for me!
