Chickens don't share our human sense of race or color as you've obviously found out. A hen perceives a difference in her chicks and then she acts on her perception. This is how hens have protected their DNA from nest parasites since time out of mind. The problem was not that she had a black chick but that she had ONE chick that didn't match the others. Refer back to "Chicken Math."Odd. This was the only dark colored chick...maybe that was it? Which is funny, because Fanny is black as pitch!
