I think it's a game that's played publicly between two groups of people who send their cocks in the fight (after drugging that cock a sip of alcoholic beverage) to give a hard and long fight, but I don't know if there's a casino that offers it. These games are not displayed in TV as well because people think that such games are insane, even they won't display bull fight, bull races and lots of other things that are available in this world but are tagged as insane, which is why due to no high recognition of the game, casinos also don't prefer listing such fights.
Excuse, what do you mean when you say alcohol is used in cockfighting, on the animals themselves? I had never heard anything like that before.
Ideally the owner of the roaster would prefer if it is completely aware of its surroundings and can focus on fighting, giving alcohol to an animal against its will and then forcing them to fight to death sounds even worse than most of the stuff I have read in this thread.

What country are you from, by the way? Have you personally seen people doing that before betting on roasters or it is only you have only heard about it?
