Frankly, I'd get rid of the leghorn and one of the orpingtons. The leghorn because of his aggressiveness, and one of the orps because of the amount of hens you have. Or, you could do as previously advised and eat all three roosters. I would not keep an aggressive rooster around when you have a child that comes to visit and likes to help with chores. It would only take once for him to scar her for life. I also would not tolerate having to carry a rake around with me to do chicken chores. Part of the reason I keep chickens is for the enjoyment of it. I would not enjoy having to fend a rooster off with a rake. If I don't enjoy the bird, it's gone.
PS - canned chicken is delicious! Labor-intensive and you may want to have several to butcher and can to make it worth your while, but it is very good and handy to have on hand.
