Pokemon-go – Does the XP bonus from the XP event stack with a Lucky Egg

The lucky egg is just an item, and does not need to be used in an incubator.

As for eggs themselves, it seems unlikely that you are simply unlucky enough to never get an Egg. From the Pokemon tab, if you swipe to the left or click "Eggs" at the top, you will see your egg inventory. If you have earned any without knowing it, they will appear here.

I have done this multiple times, and I know that the experience is applied appropriately. I kept count of the amount of Pokémon I evolved and how many did/did not gain the XP bonus.

This experiment was carried out by not exiting the menus until I had completed the evolutions, as well as timing the applicable duration of the XP boost. Additionally, all of these Pokémon (and their evolutions) had already been added to the Pokédex, so no additional bonuses were gathered (however, from additional testing this is also appropriately applied).

Pokémon evolved under the effects of the Lucky Egg:

• 12 Pidgeys
• 4 Rattatas
• 2 Zubats
• 1 Oddish
• 1 Paras
• 1 Caterpie
• 2 Weedles
• 1 Slowpoke

Total XP: 24000 (1000 XP per Pokémon)

After 35 mins (to make sure that the effect had ended) of applying the Lucky Egg - Pokémon evolved without the Lucky Egg

• 2 Pidgeys
• 1 Rattata
• 1 Psyduck
• 1 Goldeen

Total XP: 2500 (500 XP per Pokémon)

Upon exiting to the map, I levelled up, and was greeted with a counter of 26500 XP.
