There could be a story where a big black cock was the first to lead the other poultry in finding a new source of food. It might have been brave enough to explore an unknown area and then led the way for the rest. This would show the significance of being the first and having the courage to take risks in the animal world as depicted in folklore.
I'm not sure there are many common 'big black cock farm' stories in a general sense. However, if we consider a regular chicken farm with black cocks, there could be stories about their growth. For example, how they are raised from chicks, how they adapt to the environment, and the daily care they receive from the farmers.
There was this time when a young girl visited a rural fair and saw a big cock (again, a rooster) for the first time. It was participating in a show. The rooster's size and the bright colors of its plumage were so striking. She was so excited that she decided to learn more about different breeds of roosters after that encounter.
Literature should be a source of positive values and inspiration, not a place for inappropriate content.
If 'big cock' is a symbol in a more abstract way, perhaps in a cultural or local context. There could be folktales where the main character has an over - sized or special item (represented as a 'big cock') that gives them power or causes problems. But again, this is all speculation without a clear definition of what 'big cock stories' really are.
I'm not sure specifically what this 'first big black cock story' refers to. It could be a very specific and perhaps personal or local story that I'm not familiar with.
In the animal kingdom, peacocks are known for their large and beautiful tails which can be considered a kind of 'big' feature. The male peacock spreads its large tail feathers during courtship displays to attract females. This is a story of how a species uses a large physical attribute for mating purposes.

One 'big cock story' in some European folklore is about a magical rooster whose crow could wake up an entire village from a dark spell. The villagers believed that this rooster was sent by the gods to protect them. Its large size and bright feathers were symbols of its power.
I'm not sure specifically what you mean by 'big boy cock stories'. It could potentially refer to tall tales or adventures about boys growing up. For example, a story about a boy who overcomes his fears and becomes more confident as he grows, which could be considered a kind of 'big boy' story in terms of character development.
