Cockfighting is more of a luck-based game though your bird has a high chance of winning if it is well-trained but in the end luck should be on your side most of the time to win.
honestly I can't even understand how people who bet on these chicken fights manage to analyze a chicken to have any chance of winning the fight, because there is no data available on the internet about the chickens, because I don't see how they would collect data from a chicken, for example, is there a database where they put which chicken X is so many years old, has so many victories? in addition to the fact that the governments of most countries condemn this type of thing, so I suppose that those who bet on it are people who like clandestine betting, I hope that those people who organize this type of thing change their attitudes and stop doing it doing that kind of mean thing, in my country they never did that kind of thing and from what I see the law doesn't allow that kind of thing to be done. I wonder: if you took a poll of all the people in these countries who do these kinds of things, would the majority of people vote in favor of this top of things? As I have never been to that country, I cannot give an opinion on how life is in these countries.
