Chickens. Those fat little birds crowded desperately into farm sheds. Scrawny scavengers roaming the streets of third world countries. Delicious grilled, fried, or baked. Humans have eaten chickens for thousands of years. Chicken breasts, wrapped in shiny plastic packaging in the supermarket. Chicken legs, barbecued in the backyard on a sunny summer afternoon. But chicken heads, roasted on a stick? Are they delicious, delectable and juicy? Should you pounce on one the moment you see it? It’s up to you! I did, in Chaing Mai, Thailand!
