Hatched Ekans from a 5 KM egg so that is another old egg. I only have one potentially old egg left now, as all the others are 2 KM and 10 KM egg which I didn't have when the generation switched. Going to hatch that one now, after which I'm sure I only have Gen 2 eggs.
You really one need the two strongest per hat, one as pikachu and one as Raichu.I have so many Partychu's, add in Santachus, they're taking up around 100 slots of my 550 mon storage, add in 50 Porygons aswell. I cant seem to push transfer on any of them.
