I must admit that when I accidentally ended up with three chick roosters (cockerels), I got a kick out of watching them squaring off to each other and going at it as they grew up. I eventually got rid of them only because I already had a rooster and didn't need three trouble makers in the flock, and that's what you get when you have more than one rooster. But till then, it was entertaining watching them going at it with each other. Of course, I never took it to the next step of attaching razors to their spurs, so none of them were actually harmed in the matches. None of them had yet to even develop spurs, in fact. But it's deep in their natures to fight each other.
