Okay the big question is - What do the chickens look like?
Cockfighters only breed gamefowl, as they're the only breeds that will do the job well.
Because otherwise, people into fighting do indeed keep lots of hens, usually they're in separate pens or even running loose, it all depends, but also normal breeders keep lots of roosters too.
