Rocketbird Fighting

Rocketbirds, also known as Mecha-Chickens, are roosters outfitted with metallic armor, exoskeletons, and sometimes light fireworks to use as ranged projectiles.  Such roosters are often pit against each other for sport, in an illegal practice known as "Rocketbird Fighting".  Such events are difficult to find, but are held in most civilized places on the Prime Material Plane.  They often coincide with gambling and/or trade in illicit goods.
