If I breed my solar eevee with another pokemon in the fairy egg
group, can I get a shiny solar eevee? Would there be a risk of
breaking my chain and should I just get another solar eevee? Thank
you!
The parent Pokemon do not change your chance for a shiny. BUT if
you breed a Solar Eevee with a different Pokemon (except for
Ditto), you will get Eevee eggs, Solar Eevee eggs AND the other
parent Pokemon eggs.
When hunting Event Pokemon, you should always scan the eggs before
adopting, because even if you use 2 Solar Eevees, you will still
get mostly Eevee eggs and rarely Solar eggs. Hatching an egg that
is NOT a Solar Eevee WILL break your chain.
