I have hatched two shinies, both for friends.
First was a shiny Froakie with maybe 2 or 3 or 4 perfect IVs (don't remember), unfortunately it had torrent. ;c That one took 1018 eggs.
The next was a shiny Ralts. That one had 3 perfect IVs I think. (as you can see, I wasn't out for perfection) Unfortunately, it was a boy. My luck sucks. That one also took more than a thousand eggs: 1237 eggs.
I tried hatching a third one, a shiny Shinx for a friend, and I hatched 1129 before reeeaaallly slowing down because my 3DS was having awful issues (it's in for repair now) and was getting very discouraging and boring. I'd like to finish it once I get my 3DS back though D:
My plans were to hatch a shiny Vulpix and Eevee for myself afterwards. I have always wanted a legit shiny Ninetales ]: It's my absolute favorite shiny. And I think shiny Sylveon looks pretty neat. Kind of fits as a male too in my opinion, especially with the little bowtie hehe.
