Perhaps if 'cocks' was a local or made - up term for something, it could mean that mom has many stories about that particular thing. But without further clarification, it's difficult to be certain.
It could be a story set in a rural or farm - like setting. The two cocks might be real roosters on a farm, and the daughter could be a girl living on the farm. Maybe the story is about how the actions and behaviors of the cocks somehow impact the daughter's life, like waking her up in the morning, or being part of some adventure or misadventure she has on the farm. But again, this is all just guessing without any prior knowledge of the actual story.
It's highly unlikely that 'two cocks twilight fanfic' is a popular fanfic. The name itself is rather strange and not in line with the typical fanfic titles that are more mainstream and appealing to a wide audience. Most popular Twilight fanfics usually focus on well - known characters' relationships, new story arcs that are still within the general tone of the original series.
I'm not entirely sure specifically what a 'two cocks twilight fanfic' is about as it could be a very niche or even an inappropriate and non - canon take on the Twilight series. However, generally, a Twilight fanfic might be about re - imagining the relationships, characters, or events in the Twilight universe in a different way. But this title with 'two cocks' seems rather odd and might be something that goes against the general tone of the original Twilight.
I'm not sure there is a well - known specific story named 'two cocks one daughter'. It could be a very unique or made - up title that I'm not familiar with.
Another option could be 'two magnificent cockerels at once'. We can imagine a story where two magnificent cockerels are showing off their plumage to attract the hens in the coop.
Well, perhaps she was walking in a park that usually has no poultry, and then out of nowhere, two cocks showed up, strutting around. It could be that they escaped from a nearby farm or someone was illegally keeping them in the area. She would be understandably surprised at this unexpected sight in an urban - like park setting.
Another interpretation could be that in a rural or farming context, perhaps she was planning a certain activity in a yard or coop and suddenly found two roosters there which disrupted her plans, so she was surprised. This kind of situation might happen if there was a mistake in penning the animals or if some new ones were introduced without her knowledge.
I'm sorry, but I'm not familiar with this specific 'fanfic'. It could potentially be about two characters symbolically represented as 'cocks' in a situation during twilight in the context of the fanfic's story world.
