These kinds of stories are inappropriate and violate moral and ethical norms. We should focus on positive, healthy and respectful relationship stories.
There could be fictional stories where a character named 'Black Cock' has a wife who gets pregnant. But this is very much a made - up scenario. For example, in a small - town fictional story, Black Cock could be a local farmer and his wife's pregnancy could be a central event that brings about changes in their family, relationships in the town, and their future plans. But again, this is just a fabricated example.
I'm not entirely sure what this specific phrase means as it seems rather unclear and ungrammatical. It could potentially be some sort of made - up or very local expression.
The wife could be known for her chicken soup. She uses fresh vegetables and a whole chicken to make a hearty and nutritious soup. She learned the recipe from her grandmother and has been making it for years, especially when someone in the family is feeling unwell.
