Imagine a story where a rooster named Red is the hero. Red lives on a small farm. One day, a big storm is coming and all the animals are scared. Red, being the bravest, goes around the farm and encourages all the other animals to take shelter. He uses his loud crow to guide them to a safe place. He also stands guard at the entrance of the shelter to make sure no one is left behind. In this way, Red is the cock hero in this story, showing courage and leadership during a difficult time.
In some folktales, there are roosters that are considered heroes. For instance, a rooster that warns the villagers of an approaching danger like a flood or a band of thieves. The rooster crows in a way that is different from its normal crow, and the villagers, who understand the rooster's special signal, are able to prepare and protect themselves. So this rooster becomes a hero in the story through its unique ability to communicate danger.
One example could be Chanticleer from Chaucer's 'The Nun's Priest's Tale'. Chanticleer was a proud and handsome rooster. In the story, he had a dream about being attacked by a fox, but at first, he didn't listen to his wife's warning. Eventually, he outwitted the fox when the fox tried to carry him away, showing his cleverness and thus being a kind of hero in the tale.
