Raising chickens seems a difficult task for teenagers. Gracie Goodpasture, from Virginia, US, not only raises them, but also tries to breed (喂养) the “perfect chicken”. And she even won an award for her love of science.

      Gracie started breeding chickens in her third grade at Steward School. At first, she worked on some farms for her school project. But later, the 14-year-old started to have some ideas of her own.

    “Some have thicker eggshells (蛋壳), and they're hearty (健壮的) throughout the winter,” said Grade.

      Since then, the young science lover started to try to find the healthiest free-range (散养) chickens. And she ended up breeding a type that now bears her name.

      The National Science Teachers Association (NSTA) gave the 2015 Angela Award to Gracie Goodpasture. Her interests don't end with chickens and eggs. She is also into building robots and testing preservatives (防腐剂) in fast foods. In her words, she wants to go to Virginia Tech for poultry (家禽) sciences in the future.
