I agree with Shadrach, if you train before aggression, much better results. If you have a large flock, a large amount of space, and roosters in a multi-generational flock you have much better luck. Often times people with a great deal experience on here fail to take in account the difference between a flock of 30-50 multi-generational birds verses a flock of 5-10 flock mates.
If it is truly a backyard space, if the children are young, if it is a small coop/run you need to cull the rooster. It will not get dependably better. You will not be able to trust him.
