If you've had several roos get aggressive with you, I'm gonna say it's YOUR behavior that needs to change. You must be the dominant one, period. You say you're waiting for your young roos to attack you. Take the initiave! I'm not saying to attack them, but start now being the absolute boss. Walk toward them, make them move out of your way. Probably someone else can describe how to be dominate better, apparently it's just natural for me with animals. It doesn't matter if it's a thousand pound horse or a ten pound rooster, you have to make them think you're the boss. Make them move away from the food, don't let them eat until you allow it. For no reason, chase a roo a little bit, just enough to make him run away from you. Show's you're dominant.
