Description (From Recipaedia)
Creative Eggs (also known as spawner eggs as mentioned in their description) are a unique item that its prominent feature, as the name suggests, is to spawn creatures. Bird eggs are occasionally laid by adult birds. If you look carefully, you can find and eat them. Cooking an egg will increase its nutritional value and by extension, preservation. Non-bird spawner eggs are only available in Creative mode. To spawn an animal in creative mode, the player must throw the egg against a hard surface to smash it.
This description applies to all eggs.
"Spawner egg. Bird eggs are occasionally laid by adult birds. If you look carefully, you can find and eat them. Cooking an egg will increase its nutritional value. Non-bird spawner eggs are only available in Creative mode. To spawn an animal in creative mode, throw the egg against a hard surface to smash it. Some exotic animal spawner eggs are unavailable even in creative mode."
Exotic animals
Some animals have no spawner egg even in creative mode.
- White Tiger (Found in cold biomes only)
- White Bull (Found in cold biomes only)
- Orca (Found in the ocean only)
- Beluga Whale (Found in the ocean only)
Some eggs cannot be used in-game. Therefore, you can replace the egg in hand with this value by editing the Project file.
- The Orca Spawner is encoded as 12058742.
- The Beluga Spawner is encoded as 12320886.
- The White Bull Spawner is encoded as 1572982.
- The White Tiger Spawner is encoded as 6291574.
Bird eggs
These eggs are rarely laid by their respective birds. They can be cooked in a furnace with a water bucket, or eaten raw. They can also function as spawner eggs even in Survival mode, however not guaranteeing a spawn every time. Laid eggs work differently compared to those that are directly found in the Creative inventory.

Notes
- When hatched in non-creative modes, they have a 1/3 chance of spawning.
- As of the 1.21 update, Spawner Eggs are colored according to what animal they represent.
- It has been noted that after some updates, ostrich or cassowary eggs may turn into different spawner eggs such as gnu eggs, donkey eggs, reindeer eggs, moose eggs and blank eggs (if you have a world with version 1.28 or earlier containing seagull eggs it will turn into eggs that spawn White Bulls).
- Like magnets and boats, if you spawn a large amount of creatures a message saying "Too Many Creatures" appear. See the page on animal spawning.

The message saying "Too Many Creatures" on the inventory when spawned a lot of creatures.
