# Pecking Order

## What is Pecking Order?

Pecking Orders are a ranking system for chickens, the higher a chicken's Pecking Order, the stronger racer it is. There are six Pecking Orders in total:

S - Highest

A

B

C

D

E - Lowest

Each race also has a Pecking Order. You can only enter a chicken into a race that has the same Pecking Order.

Higher Pecking Orders have bigger prizes in some tournaments, as well as larger prize pools for their free entry races.

## POP

POP stands for Pecking Order Points. Your chicken will gain or lose POP, each time it runs in a paid entry race. The amount of POP it gains or loses will depend on its finishing position in the race.

## Promotion & Demotion

An unraced chicken will start with 20 POP. When it gets to 75 POP, it will be promoted to the next higher Pecking Order. When a chicken gets to 0 POP, it'll be demoted to the next lower Pecking Order.&#x20;

Whenever a chicken is promoted or demoted, its POP is immediately reset to 20.

A chicken can never have more than 75 or less than 0 POP.

## Minimum Pecking Order

Each chicken is assigned an MPO (Minimum Pecking Order), which is determined based on several of the chicken's traits, such as Heritage, Perfection, Stock, and others. A chicken can never go into a Pecking Order that is lower than its MPO.
