I have hope time will mellow them out. So far, I have been right in this assessment.
Every now and then I have to pick up a roo and carry him around to humiliate him in front of his hens or pullets or other cockerels/roos. It's usually a different one each time (yes, I have several roosters).
Now, not quite sure if it's really an expectation of "they'll get over it" or my usual procrastination which proves "yeah, they got over it," but nobody has gone to freezer camp. I don't plan for ANYBODY to be processed or culled or foisted off on somebody else.
My roosters aren't angels by any means, but they do know who is Boss of this flock. When they forget that, I walk 'em backwards til they give up that silly notion, or I pick 'em up and carry 'em around.
