I'm not sure what specific 'cock to cock stories' you mean. It could be some made - up or very specific local tales. Without more context, it's hard to say.
Well, in nature, male peacocks have these magnificent tails which are part of their 'cock' story. They use their long, colorful tails to attract female peacocks. The more elaborate and beautiful the tail, the more likely they are to find a mate.
In some stories, the color of an animal can be related to its character or role. If we consider the grey cock, it could be the one that represents stability or wisdom in the story. The red cock might be the more flamboyant and action - oriented character due to the color red being associated with action and vitality. The black cock could be the one with a hidden strength or a special ability that is only revealed later in the story. But again, this is all speculation without the actual story.
I remember a rooster that was always getting into little adventures. One time, it wandered off into the nearby woods. Everyone thought it was lost, but after a few hours, it came back with a group of wild chicks following it. It seemed like it had made some new friends during its little exploration.
One interesting cock story in folklore is the story of the Golden Cockerel in Russian folklore. It was a magical cockerel that could predict danger. The czar in the story relied on it for warnings, but things took a tragic turn when he didn't heed its final warning properly.
I'm not entirely sure what specific'split cock stories' are. It could potentially be some very specific or local folktales, or it might be a term used in a particular creative or fictional context that I'm not familiar with.
