As I don't know the exact 'family black cocks story', I can't share its interesting aspects directly. But if it's about real black cocks in a family, it could be interesting to learn about how the family trains them, if they do any special shows with the cocks or how they interact with other animals on the farm because of the cocks.
Since the 'family black cocks story' is not a well - known one, it's hard to point out specific interesting aspects. However, if we assume it's a story about a family's relationship with black cocks, it might be interesting to see how the family copes with any challenges related to the cocks, like diseases that might affect them or if they have to protect the cocks from predators. It could also be about the unique bond between the family members and the cocks, perhaps a child in the family has a special connection with the black cocks and there are heart - warming stories around that.
