I'm trying the Swap Breeding Method for shines in my Pokemon Sun, and I'd like to get a shiny Modest Anticipation Eevee w/ 5/6IVs to trade into my Ultra Moon file.
On my first round of this, I hatched my shiny Magikarp on my 16th egg, soft reset the game, swapped Magikarp for a regular male modest Eevee w/ everstone, collected 15 eggs into my PC and only hatched the 16th Eevee egg(shiny). It worked, however; the Eevee's IVs were trash.
I didn't wonder this until my second round but,
Could have I saved the game BEFORE the nursery helper had crossed her arms to indicate she had the 16th egg (again, this was the shiny one), hatched the Eevee, soft reset, hatched it again, and done this over and over again until it had my preferred Ability and IVs? Or are they already rolled when I had hatched the magikarp and cannot be changed? If this can work, will the Eevee still be shiny?
