cockfighting, the last noble sport

look on youtube "cock fight training", there are literally dozens of videos showing the intricacies of the training process

and since you were clearly too lazy to check wikipedia, i'll copy paste the article for you:

A cockfight is a blood sport between two roosters (cocks), held in a ring called a cockpit. Cockfighting is now illegal throughout all states in the United States, Brazil, Australia and in most of Europe.[1] It is still legal in several U.S. territories.

The combatants, referred to as gamecocks, are specially bred birds, conditioned for increased stamina and strength. The comb and wattle are cut off in order to meet show standards of the American Gamefowl Society and the Old English Game Club and to prevent freezing in colder climates. Cocks possess congenital aggression toward all males of the same species. Cocks are given the best of care until near the age of two years old. They are conditioned, much like professional athletes prior to events or shows. Wagers are often made on the outcome of the match. While not all fights are to the death, the cocks may endure significant physical trauma. In many other areas around the world, cockfighting is still practised as a mainstream event; in some countries it is government controlled.

Cockfighting is considered a blood sport by animal welfare and animal rights activists[2] and others, due in some part to the physical trauma the cocks inflict on each other. Advocates of the sport[citation needed] often list cultural and religious relevance as reasons for perpetuation of cockfighting as a sport.
