>>28279955I'm this Anon
>>28279561I'm level 23 now, but I haven't received any 10km eggs since I was around level 10 to 13. I don't like keeping multiple of the same Pokemon unless I'm evolving and I have good CPs. After I evolve and I'm satisfied with the stat, I tend to transfer any newer lower level Pokemon.
But since you asked. The Jynx and Electabuzz are the ones I hatched from those 10 km eggs. I haven't seen any in the wild. I had forgotten that the Chansey was also hatched from a 10km egg. I had originally hatched a Magmar of the same stats from an egg, but two weeks ago, I caught the 800CP Magmar and discarded the other one. The Eevee I have long since evolved. The Snorlax seen here
>>28279520 I caught the day before hatching the 10km egg, that turned out to be a 500CP one. And, well the Magikarp you see there is the 10km one I hatched; I've caught many more but none that high CP.
