Yesterday, we posted that some trainers were reporting hatching Eevees from 5km eggs. Today, Pokemon GO’s official Twitter page gave an official egg update, and it seems those reports were true.
In addition to Eevee now hatching from 5km eggs, common Pokemon like Rattata and Pidgey will no longer be hatching from 2 km eggs. Surely, veterans of Pokemon GO will rejoice, as they are all well stocked on Pidgey and Rattata candy mostly used for power leveling.
Official Pokemon GO announcement
Professor Willow has discovered that Pidgey & Rattata no longer hatch from Eggs. He also found that Eevee now hatches from 5 km Eggs only.
