Final answer:
Baby Zombies in M*necraft have a 0.25% chance of spawning as Chicken Jockeys.
Step-by-step explanation:
In M*necraft, there is a 0.25% chance that Baby Zombies will hatch as Chicken Jockeys. A uncommon event known as a "Chicken Jockey" involves a baby zombie riding a chicken. There's a slight chance that a newborn zombie will latch onto a neighbouring chicken as it spawns, resulting in this unusual and mildly entertaining hostile mob.
Chicken Jockeys are faster and more difficult to defeat than normal zombies since they have the ferocity and speed of baby zombies. There's a surprise aspect to the game when players come across Chicken Jockeys because they pose a more agile and unexpected threat.
