Pokémon Eggs

Pokémon Eggs are Pokémon-related resources which allow Trainers to obtain Pokémon. Most eggs can be obtained from PokéStops and Gyms around the world. Each owned egg contains a random Pokémon and can be hatched by walking one of five specified distances.

Kinds of Pokémon Eggs
There are five kinds of Pokémon Eggs, with different distances required to be walked. The Trainer must walk with an egg in an Incubator in order for it to hatch. Below is a list of each type of Pokémon Egg and ways to obtain them:
 * 2-km Eggs can be obtained from spinning Photo Discs at Gyms and PokéStops.
 * 5-km Eggs can be obtained from spinning Photo Discs at Gyms and PokéStops, and as an Adventure Sync reward if Trainer walks at least 25 km in a week.
 * 7-km Eggs can be obtained via Gifts received from friends. They cannot be obtained by spinning the Photo Discs at Gyms or PokéStops.
 * 10-km Eggs can be obtained from spinning Photo Discs at Gyms and PokéStops, and as an Adventure Sync reward if Trainer walks at least 50 km in a week.
 * 12-km Eggs also called Strange Eggs can be obtained by defeating Team GO Rocket Leaders (but not Giovanni). They cannot be obtained by spinning the Photo Discs at Gyms or PokéStops.

Pokémon Eggs collection
Players can see currently owned eggs in the Eggs tab under the same in-game interface location that Pokémon collection and battle parties are.

To get to the page with currently owned Pokémon Eggs in game, player needs to:
 * 1) In Map View tap on Main Menu button [[file:Button Main Menu.png|30px|link=]]
 * 2) Tap on Pokémon button [[file:White Button Pokemon.png|30px|link=]] in Main Menu
 * 3) Tap on EGGS tab on the top of the screen or swipe the page to the left.

If there are no Eggs in Trainer's collection, Egg silhouette icon and message "Collect more Eggs!" are displayed.

Hatching Pokémon Eggs
Hatching Pokémon Eggs is one of currently three ways to obtain Pokémon, the others being catching them and trading them with a friend.

Trainers can choose which Egg they want to hatch by tapping on an egg, then clicking on the button in the Egg's summary page. It will then prompt the player to choose which Incubator they want to use for the selected Egg.

To hatch an egg, the player needs to have at least one currently unused egg incubator. There are currently three kinds of Egg Incubators in game:
 * An orange one is received at the beginning of the game and has unlimited uses.
 * A blue one that can be used a limited number of times – limited Egg Incubators received for achieving Trainer levels, bought from in-game shop or rewarded from Special Research have 3 uses only.
 * A purple one that may be used three times and will shorten the walking distance required to hatch an egg by 33%.

If Trainer does not have any available Incubators, they can either buy one from the in-game shop or wait until an Egg that is currently in an Incubator hatches and thus the Incubator will be available to use again.

Gameplay can carry on as usual when hatching an egg. Distance walked for hatching an Egg in an Incubator is measured by GPS distance and location changing, not by movement or number of steps. Trainers require Adventure Sync feature turned on in order to record walked distance to hatch eggs while the game is not on screen or completely closed.

It is worth mentioning that Pokémon Go has various limits on speed (approximately 24km/h (15 MPH)). If a person exceeds these limits, the app will not register the distance traveled for incubated Eggs. Players have also estimated that when the app is open, it pings the player's location every 4 minutes and it appears to measure the straight-line distance between pings and will add that distance to every currently used Incubator with an Egg inside of it.

Once the required distanced has been walked, the egg will appear on the screen with the message "Oh?". Tapping the screen will cue eggs hatching animation revealing the Pokémon that was in the egg, then the player is led to just hatched Pokémon summary page.

With each hatched Pokémon Egg, Trainer additionally receives a number of Candy for that hatched Pokémon, XP and Stardust. The amounts of these resources depends on the kind of egg hatched.

Pokémon Eggs hatchlings
There is specified group of Pokémon that Trainers can hatch from eggs. This group of Pokémon changes with new Pokémon being added to the game or temporarily for certain events. Pokémon hatched from eggs always come with a number of their species' candy higher than what a Trainer would receive from catching it in the wild.

All Pokémon from Eggs (including their IV and Shiny status) are determined when the Egg is obtained. Thus, when the contents of eggs change (e.g. due to an event), Pokémon that hatch during an event, from Eggs obtained before the event, will not be event Pokémon. The Pokémon that you get depends on when the Egg is obtained, not when it is hatched. So, only eggs obtained while an event is live will hatch event Pokémon.

The CP of Pokémon hatched from eggs is based on the Trainer level when the egg was obtained, not when it is hatched. The maximum CP of Pokémon hatched from eggs is equal to the CP on Pokémon level 20.

Changes
Since the release of the game, there have been several changes to distances and the list of Pokémon that could be hatched from eggs. Most of these changes occur due to major releases of new Pokémon or temporarily for the duration of a specific event.

Hatch Rarity Tiers
Starting on March, 2021, a limited number of Trainers can see a list of possible hatches from an Egg by tapping on it. The likelihood of hatching each of the available Pokémon is ranked in rarity tiers from 1 to 5, where 1 has the most common species and 5 has the rarest ones. On April, 2021, this feature became available to all Trainers.

Trivia
