Correct me if I'm wrong, but...

Didn't people in the Human Realm make chickens fight as fortune-telling or something?

Cockfighting?

I see! That way we could decide the gods' will.

Well, I'm a god, though...

Cockfighting Since before the Asuka era, ritual cockfights would be used for fortune-telling. As time went on, the gambling element became more central.

We don't even have any chickens of our own.

Don't tell me you mean to send out Piyo-chan?
