Task List/hatch lv1
Pick up some Eggs from the Lab or Shelter and let the fun begin! But remember, the Shelter only allows you to adopt 6 Eggs or Pokémon daily as long as you don't buy a higher Shelter Pass. However, the Lab will always provide you with Eggs and help you to fill your PokéDex.
Don't forget that Eggs with a higher EXP take longer to hatch!
