Egg

Eggs are items that can be used to craft food items, or used as a throwable entity.

Chickens
Chickens lay eggs every 5–10 minutes and these can be collected while on the ground.

However, black chickens, that have a 0.69% chance to spawn instead of a regular chicken, lay fried chicken every 5-8 minutes. You will hear the chicken shout 'LEEEROY' when this occurs. The chicken can be collected from the ground.

Combat
Players are able to throw eggs and deal knockback to mobs and other players, but no damage will be dealt. Throwing eggs at neutral mobs will provoke them. Eggs can also be fired from dispensers and are affected by gravity.

Spawning chickens
When thrown, an egg has a $1⁄8$ chance of spawning a chick. If this occurs, there is a $1⁄32$ chance of spawning three additional chicks (on average, 1 out of every 256 eggs will spawn 4 chicks).

Trivia

 * Eggs will break midfall if hit by another projectile; the chance of spawning a baby chicken is not affected.
