Chicken Jockey

Chicken jockeys are the rare appearance of a baby zombie, baby zombified piglin, baby zombie villager, baby husk, or baby drowned riding a chicken.

Spawning
Each baby zombie, baby husk, baby zombie villager, baby zombified piglin, or baby drowned that spawns has a 5% chance to check for an existing chicken within a 10×6×10 box centered on the baby's spawn location and spawn riding one of those chickens if there are any. If it fails that 5% chance to check for existing chickens, there is an additional 5% chance of the baby zombie spawning mounted on a new chicken. In a chicken-free environment, each spawned zombie has a 0.25% chance of becoming a chicken jockey; if chickens are present, the chance increases to 0.4875%.
 * Java Edition

Chicken jockeys may spawn with items equipped. Baby zombified piglin versions of the chicken jockey always have a golden sword equipped, while baby drowned versions may have a trident. Although chickens take damage from magma blocks, baby zombified piglin jockeys still spawn on them, killing the chicken and leaving just the baby zombified piglin. Provoking the zombified piglin chicken jockey causes it to attack, like a normal zombified piglin.

$$, there is an extremely low chance for a baby zombie villager to spawn wearing enchanted full diamond armor and holding an enchanted iron sword while riding a chicken; this chance is 1 in 1.9921&times;1035, making this mob the rarest in the game.

Using the summon command: yields a chicken jockey.

$$, baby zombies, baby husks, and baby zombie villagers have a 15% chance to become a jockey when it tries attacking a villager, player, or iron golem, which can ride: • Adult chickens
 * Bedrock Edition

• Adult ocelots and stray cats

• Adult wild wolves

• Adult zombies and variants

• Cows

• Pigs

• Sheep

• Horses and variants

• Mooshrooms

• Spiders

• Cave spiders

• Pandas Any rideable or tameable mob can become unrideable or untameable, respectively, after being mounted by a baby zombie.

$$, if a baby zombie has spawned on another type of mob (such as an adult zombie), killing the baby zombie's current mount in an area populated with chickens may result in the baby zombie jumping onto a chicken rather than attacking the player. In addition, Baby Zombies riding on other zombie variants appear to have a chance to change into the baby variant of the mob it's riding.

Behavior

 * Chicken jockeys generally run around, behaving like the zombie, instead of using the chicken AI.
 * Chicken jockeys fall slowly and do not take fall damage, like normal chickens.
 * The chicken moves at the speed of the baby zombie, which is much faster than a normal chicken.
 * Command spawned jockeys are an exception.
 * The chicken can run through 1 block high gaps. The baby zombie suffocates unless the above block is transparent.
 * Chicken jockeys can pick up/equip items.
 * The chicken (unless spawned with commands without the IsChickenJockey tag) does not lay eggs. However, they can still be bred into regular chickens.
 * The baby zombie and the chicken can be separated by using a bucket of water on them.
 * In Creative mode, a chicken jockey that isn't already targeting a player follows a player holding seeds, like a normal chicken, and can be fed. In Survival mode, unless the zombie is a zombified piglin in a non-aggressive state, the chicken jockey targets a player who attempts to do this, and the chicken cannot be fed.

Data values
The chicken and rider's IDs nor the entity data are any different than if the chicken or rider were standing alone.

Trivia

 * The baby zombie's hitbox is larger than the chicken's. Attacking the chicken may harm the zombie instead, unless the player carefully attacks its feet.
 * Chicken jockeys, like spider jockeys, cannot pass through portals.
 * Zombified piglin chicken jockeys can spawn from portals in the Overworld.
 * A normal chicken jockey may spawn in the Nether if a zombified piglin calls a normal zombie as reinforcement.
 * If the zombie happens to be a zombie villager, curing it separates the cured villager from the chicken.
 * Name tags prevent the chickens from despawning, and they can be bred to spawn normal egg-laying, non-despawning chickens.
 * The wither attempts to attack the chicken being ridden by the zombie and the zombie also takes damage.
 * Adult zombies and zombified piglins can also control a chicken while riding on it, though they do not naturally spawn on chickens.
 * A zombified piglin chicken jockey does not become hostile if the chicken is killed or attacked.
 * Chicken jockeys spawned using  use the chicken's speed instead of the baby rider's speed.
 * To prevent a chicken jockey from despawning, only the chicken needs to be name tagged, because riders of other entities never despawn.
