Chicken fighting has become a popular sport although illegal, among all the people of Hawaii. Chicken fighting is a sport in which specially bred and trained fowls are pitted against each other in a fight usually to death. This sport is often called, blood sport because of it's fierce way of fighting. Some matches include several birds in a free-for-all until one wins. The people put some metal bone spurs on the birds' feet. This sport is very popular in Mexico, Puerto Rico and Pacific Islands. Every weekend and on holidays games are held in specific areas around the island. Chicken fighting games attract tourists, the curios, and the regular crowds. The birds are carefully trained and groomed by their owners. When two birds meet in the ring, it becomes a fight and the audience take sides cheering for the one they think will win. All you can hear are people screaming and betting. At the end of the fight, the winner triumphs while the owner of the defeated bird cuts off the foot of the chicken where the knife was attached and hands it over to the winner. At these chicken fights, vendors sell vegetables, Filipino food, sweet cakes and drinks. They even sell fighting birds.
