Chicken anime dream

I just had a really weird and vivid dream. The dream was like a cute and sad anime documentary about chickens.

According to that reality, baby chickens have this auto-detection mechanism to tell when there's some genetic problem with them, and the chicks with problems all gather into one little corner. The old crusty grandpa rooster dude then comes and kills those chicks.

So then the anime part comes. It starts at a first-year junior high class in a town full of blonde kids. But there's this one black-haired girl -- a cute tsundere who dresses in black punk clothes and never really acts like part of the rest of the class. But she has a crush on this guy in high school.

The guy learns that she has a crush on him and also that she has never been accepted by her peers, so he develops a sort of sympathy toward her. For a few weeks, they meet and talk, and the guy tries to help her through some of her problems. He learns that her biggest problem is her grandpa who just hates her. So one night, the guy tells her he's going to visit her house the next day to meet with the grandpa.

She goes home alone that night, and the grandpa is at home waiting for her. He asks why she was out so late, and she puts on this "none of your business" attitude. The grandpa then strikes her to the ground and proceeds to beat her to death.

The guy comes to the house the next morning, and is greeted by a smiling blonde-haired family. He asks where the girl is. The father explains that they have never had such a girl living there.
