Cooked Chicken is obtained by cooking raw chicken, which can be acquired from chickens when they are killed. Consuming this item restores a player's hunger points and provides a temporary boost to their hunger saturation, which delays the need to eat again. It is a reliable food source that can be easily farmed, as chickens are a common passive mob that can be bred for a continuous supply of raw chicken and feathers.
