"Roosters have no concept of being embarrassed."
I truly must disagree. I had one nearly adult roo (around this fellow's age) that got his butt kicked by an older rooster in front of the whole rest of the flock, and he ended up hiding in a corner of the coop, refusing to eat or even move. I had to remove him, hand feed him for several days, slowly reintroduce him first to a very timid pullet, then another, a bit at a time for a few days at first. I literally had to build up his self-esteem again.
After a couple of months, you'd never know there had been a problem, but I know for certain that roos do, absolutely, have a concept of embarrassment. I believe what I saw with my own eyes.
