For the duration of the Easter event, you will receive double XP from all sources - this includes
catching, hatching, and evolving Pokémon, as well as spinning PokéStops.
This double XP stacks with the Lucky Egg, which can combine to give you 4x the usual XP when playing the game.
This means you'll get an egg-celent 2000 XP every single time when evolving a Pokémon with the Lucky Egg active.
Hopefully you've been saving up your Pokémon that only take 12 candy to evolve: Pidgey, Caterpie, and Weedle!
Increased candy from hatching all eggs
While the Easter event is active, you'll receive egg-stra candy for hatching any of the eggs: 2k, 5k, and 10k eggs.
Along with the double XP, and more varied Pokémon from 2k eggs, now is the perfect time to get walking!
