When I get a roo who thinks he's going to boss me around......he quickly learns that it wasn't such a good idea. The trick is to keep in mind.........ALL of the hens are YOURS. The coop is YOURS, the run is YOURS, the food is YOURS. When you are around, he's not allowed to mate the hens, be first at the feeder, cross your path, or do anything that could be even remotely perceived as dominance in your presence. If he comes up to you....chase him off. If he makes a mad dash for the feeder... Chase him off. If he is mating a hen nearby....boot him off. It's got to be tough love with aggressive prone roosters. Once they know that you aren't going to tolerate rude behavior, they meekly....almost casually......turn around and walk in the other direction when they see you coming. That's the way I like my roosters. They leave me alone and I leave them alone.
