I recently got my shiny charm from trading through Pokemon Home. I have been shiny hunting Sprigatito for about a week now (roughly hatched 700 eggs) and not a single shiny yet. These are the 2 Pokemon I've been using:

JAP Ditto (recieved from a Home trade, originated from Pokemon Scarlet)

ENG Sprigatito (the promotional Sprigatito given to me for linking Home to my Pokemon Violet save. Originated from Home)

I used this Sprigatito because my original Sprigatito doesn't have the ENG tag in their summary screen. My original starter was Sprigatito but it has a blank language tag. This saves language is English as I'm American.

Am I doing something wrong? Incredibly unlucky? 1:512 odds seemed easy a week ago
