I've got a very beautiful EE rooster that is very aggressive toward me and is very rough with my hens. In fact, I think he seriously wounded a hen whose neck I sutured up after a Pull-it Shut chicken door accident. The scar on the back of her neck wasn't just re-opened, there was skin missing. I had to put her down. He was also mercilessly flogging the other hen I separated because of a wounded vent then re-introduced. He has a couple of favorite hens whose saddles and comb areas are bare of feathers from his rough rides.
I've got him separated in his own temporary 4'x4' cage, but the wife is pressuring me to either kill him, build him his own coop and run, or give him away. He's a mean SOB, and I only keep him around because he is so beautiful. I thought about sending him off to a freeze-dry taxidermist, but that's a few hundred dollars, and my wife won't let me keep it on my dresser. ;-)
What would happen if I reintroduced him to the flock? Is he now at the bottom of the pecking order, or would he be back to his rough ways in no time flat? I'm not terribly concerned with the bare patches on one or two hens' saddles, but I won't tolerate him flogging my favorite hen.
