Chicken

Chickens are common passive mobs found in grassy biomes.

Spawning
Chickens spawn naturally in groups of four on grass blocks with 2 blocks of free space above it at a light level of 9 or more.

Chickens are more common in jungle hills, jungle edges and modified jungle edges.

After the world generation, they spawn individually.

5% of chickens spawn as babies.

They require a light level of 7 or more to spawn and are found in groups of two to four.

Java Edition
All baby zombie variants and baby zombified piglins have a 5% chance to spawn riding a chicken, forming a chicken jockey. Because a baby zombie occurs from 5% of zombie spawns, the chicken jockey spawns consist of 0.25% of all zombie spawns in a chicken-free environment; if chickens are present, the chance increases to 0.4875%. A chicken jockey can also be spawned by using the following command:

Chicken jockeys may spawn with items equipped. Baby zombified piglin versions of the chicken jockey always wield a golden sword. Harming or killing the chicken does not cause the zombified piglin to attack.

Bedrock Edition
Baby zombie jockeys no longer spawn riding chickens, but check for nearby adult chickens to mount prior to attacking a player, wandering trader, adult villager, snow golem or iron golem.

Drops
When an adult chicken is killed, it drops:
 * 0–2 . The maximum is increased by 1 per level of Looting, for a maximum of 0-5 with Looting III.
 * 1 (1  if killed while on fire) The maximum is increased by 1 per level of Looting, for a maximum of 1-4 with Looting III.
 * when killed by a player or tamed wolf ( if it was part of a chicken jockey).

They also lay 1 every 5 to 10 minutes.

Upon successful breeding, is dropped.

Killing a baby chicken yields no items or experience.

Behavior
Chickens wander aimlessly, chicks also follow adults. When falling, they flap their wings and fall slowly, thus they are immune to fall damage. However, they avoid falling off cliffs. When harmed, they flee around. Chickens uniquely attempt to jump up to climb stairs instead of climbing them normally. They are attacked by ocelots, untamed cats, and foxes. Chickens follow players holding various seeds within 6 blocks.

While in a loaded chunk, a chicken lays an egg every 5-10 minutes (6000-12000 ticks), unless it is, or was, a part of a chicken jockey. If the player is close enough to a chicken when it lays an egg, a pop sound is heard.

They swim, visibly flapping their wings and staying on the water surface. While swimming, chicks need only one block of air above their heads. Full-grown chickens need two blocks of air above their heads or else they are harmed.

Breeding


If two adult chickens are fed wheat seeds, beetroot seeds, melon seeds or pumpkin seeds, a baby spawns. They cannot breed for 1 minute afterward.

Baby chickens take 20 minutes to grow up, but the growth time can be accelerated by 10% each time it is fed seeds.

Baby chickens do not lay eggs. Due to their small size, they can pass through openings even smaller than a full block, though not willingly.

Thrown eggs have a $$ chance to spawn a baby chicken. If successful, there is a $$ chance ($1⁄8$ per egg) to spawn 4 baby chickens instead.

Entity data
Chickens have entity data associated with them that contain various properties.

Trivia

 * When a chicken is riding a minecart, it is impossible to attack the chicken as it is completely inside the minecart's hitbox.
 * When a chicken is killed while falling, the corpse also falls more slowly than normal, and the wings still make a flapping animation.
 * Chickens are able to "hide" within hoppers due to their small size, protecting them from lava or water that might be directly on top of the hopper.
 * Chickens are the only Overworld mob (without the use of hacks/inventory editors) that can breed without a separate item farm, by building a suitable area, collecting their eggs, and throwing the eggs back onto the ground. See also chicken farm.
 * A few weeks before the end of Java Edition Beta, Notch tweeted that he changed the chickens to ducks, causing a turmoil on Twitter. A few days later, Jeb, still getting feedback on the idea, stated that it was just a joke.
 * The changelog for Pocket Edition v0.3.0 alpha referred to chickens as ducks.
 * Notch later referred to chickens in a blog post as "the chicken/duck/whatevers".
 * If the player throws eggs at glass panes, there is a small chance for the baby chicken to spawn on the other side of the panes.
 * If an egg is thrown into the water, there is still a chance for a chick to spawn.
 * Chicken corpses can also lay eggs.
 * Chickens spawn more frequently in jungles than in other biomes.
