If you wear shorts at any time, freckles, moles, bruises or scabs on your legs will become the focus of pecking. It's a curiosity thing. Same things with rings on your fingers, buttons on your clothing, or a bit of fluff that just happened to land on you.
Ditto for earrings. Some folks have lost expensive gemstone ear studs.
Don't let your beloved chicken(s) get too close to your face if you are not wearing glasses. Eyeballs are shiny. Chickens peck at shiny things.
