Managed to hatch a shiny Salandit while breeding for perfect dads! It wasn't even Masuda Method!
I've been trying to get 6IV male parents from every egg group and I'm nearly done, but using Pokemon with biased gender ratios REALLY helped. I learned my lesson after 5 perfect female Feebas and 300+ Feebas eggs.
Thankfully I was able to evolve the male Salandit into Salazzle through The Trans Rights glitch so... Trans Rights!!
