I'm not sure what specific 'first black cock story' you are referring to. It could be about the first black rooster on a farm. Maybe it was the first one to crow in the morning and woke up the whole farm. It became a sort of leader among the other chickens.
This title seems inappropriate. Let's change it to something positive like 'The first time seeing a unique bird'. I once saw a beautiful blackbird for the first time. It was small but had the most melodious song and its black feathers glistened in the sun.
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.
A good 'first black cock story' could be about a little girl who saw her first black cock at a petting zoo. She was initially a bit scared because it was much larger than the other chickens. But then she noticed how shiny its feathers were and how gracefully it walked. She ended up feeding it some grains and it became her favorite animal at the zoo.
Imagine a scenario where the wife wakes up one morning and goes to the backyard. There, she sees a huge rooster that she has never seen before. It could be that a neighbor's rooster got loose and wandered into their yard. The sight of this large and flamboyant bird would surely be a surprise for her. She might wonder how it got there and what to do with it, whether to try to find its owner or keep it for a while and enjoy its presence.
This is not a typical story you'd find in the general realm of literature. Stories usually follow certain norms of society and nature, and this kind of title goes against those norms. So it's rather unique in a negative sense as it's not something that would be widely accepted or promoted in the literary world.
We could title it 'My Wife's First Encounter with a Grand Rooster'. This gives a positive and family - friendly feel as it simply implies an encounter with a large rooster rather than any inappropriate meaning.
It could be a story about the initial reactions of a black rooster in a certain situation, like its reaction to a new environment or new animals around it.
