Killing Monkeys and Fighting Chickens

This is a world of cockfighting. As a descendant of dinosaurs, they have hollow bones, walk on two legs, fly with wings, and breathe with sac lungs... Chickens can walk where monkeys can walk, and chickens can fly where monkeys can't fly. After 100 million years of evolution, I would like to become a fighting chicken and lead the descendants of dinosaurs to fight monkeys to the end.
