I'm pretty sure they're pecking at a lit up board or something, like Lee suggested. I've seen them before. But, Brett, it's nothing to get uptight about. It's just good ole fun. I've seen several of these Skinner boxes at a theme park in Texas. They were fun. You popped in a quarter to play tic-tac-toe against a chicken. Some would play a piano or things like that. They were just cute, not a "scam".
