A Cooked Egg is the result of cooking an egg over Fire. In most cases, this will take place at a Campfire or Fire Pit as a result of the player "Cooking" the Egg (a Star Caller's Staff can also be used). In some cases, an Egg may be cooked due to a Mob being set on fire.
Cooked Eggs can also be used in Crock Pot recipes, or given to Pigs or the Pig King. Feeding a Cooked Egg to a bird in a Birdcage will yield a fresh Egg; this way, spoiled Eggs can be reused indefinitely.
Meats that are not accepted by the Pig King can be converted into Eggs by the bird in a Birdcage, which are accepted in exchange for Gold Nuggets.
Spoiling Meats can be saved from turning into Rot by converting them into fresh Eggs.
Crock Pot recipes using Eggs can replace many recipes that use meats if the player has a Birdcage.
Giving two cooked Monster Meat to a Caged Bird will give two Eggs. These Eggs, along with one Morsel and one more Monster Meat will result in Bacon and Eggs. (75 Hunger and 20 Health from 3 Monster Meat and 1 Morsel).
When Eggs/cooked Eggs are starting to Spoil, they can be given to a Birdcage to make them fresh again. However, one can only give the bird cooked eggs in order to receive another egg.
Unlike other meats, raw eggs will not lower sanity when eaten.
