You know, roosters can get pretty big but in my experience, the bigger they are, the sweeter they are. Unless they're cross breeds and one of the crosses was a Polish or something. At my house aggressive roosters are called "dinner". But some just need a little reminder whose the alpha rooster (that would be me)...kick them across the yard a few times...with some that's all you have to do. If that doesn't work, well you just wait til morning and get them before you open the coop door. Grab them by their legs and carry them upside down so they stop struggling. Hold the rooster in one hand, the .22 in the other and shoot the ****er in the back of the head...stops an aggressive rooster every time. Banty's are mean little pricks...like most metrosexual DUmmie males they've got that "little" man complex...and you can't sex them before they hatch like other breeds. Of course, I've never had a 3' rooster. I have Henry, a Buff Brahma, 2 Blue Cochins, My Babushka and Beauregard, and 2 Cuckoo Marans, Jester and Max and they're all big ***** cats (they also father the most chicks because they're really sweet to their hens...which proves the adage about attracting more flies with honey). They're large breed...Henry and Jester may be 2' tall, but if you see a 3' rooster, I think you probably ate the brown acid. Anyone who keeps a mean rooster around is an idiot. You want a guard bird get guineas, geese, or peacocks.
