This isn’t always the case.

I had a salmon flaverolle rooster, one of the stereotypical cockfighting breeds, known for their aggression and beautiful plumage.

A raccoon got into the coop and mortally wounded one hen and killed the hen that was the only one to stand up and fight, a silkie. Silkies are tiny fluffy luxury birds with fluffy feathers on their feet, they don’t have good meat and lay eggs with a diameter smaller than a quarter. She was the only hen that scared the rooster because she beat the hell out of him when he tried to breed her a few times. She ruled the roost with tiny fluffy feet and handled disputes between birds 3-4x her size without issue.

The rooster? Unharmed entirely and found cowering on the top roost. He wouldn’t fight a raccoon, but he would always try to disembowel me when I went into the coop.
