Actually I don't like betting for animal or human fights.
But I have experience with this bet kind.
To start cock betting, I have to look at the details of the chicken, ranging from physical, feathers, shape of the paws, to the owner of the chicken (this relates to how the owner care of the cock)
If you are into this then i could say that you are a cockfight enthusiast. It's hard for beginners to distinguish a good quality cock/bird by just looking at it's aesthetics and you are able to do this which means you are a pro on this game
.
If cock-fighting bet doing by online, I doubt to make any bet b'cause I never know physically of the cock.
You have to really rely on luck on this matter but they will put the owner of the cock so this might give you some tip on where to bet.
