Pokémon Eggs are Pokémon-related resources which allow Trainers to obtain Pokémon. They can be obtained from PokéStops around the world. Each owned egg contains random Pokémon and can be hatched by walking one of three specified distances.
Kinds of Pokémon Eggs
There are four kinds of Pokémon Eggs, with different distances required to be walked. The trainer must walk with an egg in an incubator in order to hatch it. These three types of eggs can be obtained from Photo Discs at Gyms and PokéStops:
- 2-km Eggs,
- 5-km Eggs
- and 10-km Eggs.
There are also special 7-km Eggs that can be received via Gifts sent by Friends. These eggs will hatch Fossil Pokémon currently. They cannot be obtained by spinning the Photo Disc at a PokéStop or Gym.
When the game was released, all three kinds of eggs had the same in-game appearance: cream-white egg with pale-green spots on it. As of October 23rd, 2016, with the release of update version 0.43.3, 5- and 10-km Eggs gained a different appearance, with their spots becoming orange and purple respectively.
