Before any Pokemon GO Raid starts, the boss Pokemon has to hatch from a Raid Egg after a countdown ends. Each Tier of Raid has a different Egg, and with Primal Raids finally arriving in Pokemon GO, a new type of Egg has also come to the game!
Primal Eggs are orange and appear to have Primal Energy surging through them.
On one half of the Egg, there is blue energy for Primal Kyogre, and on the other half of the Egg, there is red Primal Energy for Primal Groudon. This gives Primal Eggs a very distinct look and makes them stand out from other Raid Eggs!
So you don’t confuse these with any of the other Eggs, find out what every Pokemon GO Raid Egg looks like!
Of course, after the timer runs out, either Primal Groudon or Primal Kyogre will hatch from a Primal Egg, and you’ll be able to battle them. However, to stand a chance of winning against these Primal ‘Mon, you’ll need to prepare for the battle:

Unfortunately, there is no way of telling which of the two Primal Pokemon that a Primal Raid Egg contains until it hatches.
Therefore, you should wait until the end of the countdown to find out whether you will be able to battle Primal Groudon or Primal Kyogre at that Gym.
It’s not just the new Primal Eggs that you may not recognize. In fact, there are two other Raid Eggs in Pokemon GO that don’t appear very often:

What Are Orange Raid Eggs in Pokemon GO?
The new orange Raid Eggs in Pokemon GO are for Primal Raids. Once the countdown ends and a Primal Raid Egg hatches, it will contain either Primal Groudon or Primal Kyogre.
Another sign that the orange Raid Eggs are for Primal Pokemon is that they have blue Primal Kyogre Energy and Red Primal Groudon Energy surging through them.
