Because of the event I decided to spend 20 dollars on incubators in order to try and get Ash hat Pichu, unfortunately 2km eggs became super rare in favor of 10km becoming super common. So maybe next year. I did finish the Porygon line however. Never thought I'd say that.
On the 23rd I hatched 11 eggs, including 3 10km eggs, I got a second Porygon which I evolved, a second Larvitar which I also evolved to Pupitar, and a Skarmory. For 2km eggs I got 3, Krabby, Misdreavus and Machop. Still not sure why Natu is still hatching from eggs, 5km none the less. At one point I had 5 on my nearby tracker at one time..... Natu is the Pidgey of gen 2.
Today I hatched 17 eggs, for 10km's I hatched Miltank, Dratini and a 3rd Porygon. Disappointing overall. For 2km's I hatched Aipom, Diglett and Slugma. For 5km's I hatched my second Tyrogue, as well as Omanyte and Kabuto for rare hatches.
For eggs I mainly need Tyrogue, Chansey, Mareep and Larvitar.
