i mean i could but eggs take a lot longer than outbreak farming - i personally only plan to egg farm in this game for starters or other pokemon not available in outbreaks / isolated shiny methods!
i dont think you can change their color as far as i know?? which makes it more of a challenge but i'll end up trying eventually :')
next time i see a floette or flabebe outbreak ill see if they give their proper color or default to red/orange. i think white is the rarest color to find too lmao, our taste sucks!!
