Well....I went in there last night and didn't give him any time to decide his behavior. I decided I didn't want to look insecure or unsure, so I went in and snatched him off his roost/perch. I carried him around by his legs in front of his girls and the other rooster/hens in the other pen. He also accompanied me while I did a few horse chores - he really enjoyed helping me fill the water troughs and being upside down in the presence of the horses.
After about 10 minutes, I took him back into his coop/run and tossed him very firmly about 6 feet. He turned his back to me and went to the furthest corner of the run, and I just stood there. After a while he thought he'd like to go join is girls, and I blocked his movement by just shifting my weight forward in his direction. He returned to the far corner with his back to me. I held him there with my presence for another minute, and then I just walked away and went to finish my barn chores.
The barn is mostly out of sight from the chicken coops, but I could hear him crowing repetitively for a good 5 minutes.
I have no idea if this has worked, but I'm not fooling around. I don't want to breed forward any "crabby" jeans One more wrong move, and he's a goner. Every single other rooster I've had has been great....and I still own his brother - who isn't showing a hint of aggression.
I'll update more this weekend.
