Hah! Yes! And it was not funny.
I was pretty new to the chicken thing and had just gotten three adorable three-week old Light Brahmas. They were cuddly little lap urchins right from the start. One day, while doing some lap time, one was looking me right in the eye. I made the mistake of looking back.
Got pecked right in the eye! It hurt like hell, and I had some serious bleeding into the sclera. I made an emergency appointment at the eye doctor the next day to make sure my retina hadn't been detached. It was okay, but the macula had some damage. Then for a week, I sported a shiner.
Rule: never look a chicken in the eye.
