Cooked Chicken

Cooked Chicken (also known as Drumstick in Pirate Speak) is a food item added in the 1.8 "Adventure Update" created from roasting Raw Chicken in a furnace or by killing chickens with fire. The Cooked Chicken heals 3 units of Hunger and 7.2 units of Food Saturation, making it slightly superior to bread or Cooked Fish.

Behaviour
Cooked chicken can also be obtained by killing a chicken with fire, which is a more direct yet dangerous way of obtaining it. Eating the chicken raw only restores 1/3 [] as much hunger points and has a chance of giving you food poisoning.

Farming
Since chickens are persistent as of Beta 1.8, it is easily possible to create chicken egg farms. Put eggs into dispensers to spawn chickens automatically, then let the chickens fall onto a burning netherrack block and let them run off that block. They will burn to death and drop cooked chicken.

History
At first The cooked chicken texture was different -, but was changed after Jeb admitted it didn't fit into Minecraft's sharp textures norm.
