Valve Added pet chickens as a secondary "Trust Factor" metric. If your willing to give up weekly drop, worth real money, to take care of and feed a virtual chicken (that's sole purpose is to be cute), it likely means you are a good person.
Bot farms and cheaters will always choose money over happiness. If you take care of your chicken you will be placed in lobbies with other responsible pet owners. If you kill your pet chicken you will be doomed to low trust factor hell with spinnbotters as retribution.
You have been warned.
Jynxzi couldn't stop laughing after Dantes told him every game of League of Legends is winnable because something tragic could happen to an enemy laner 😭💀💀
