>>46001889gave up on a shiny rookidee, have the shiny charm, encountered over 1000 of them without breaking chain, nor encountering other pokemon, hatched more than 500 eggs, still no Rookidee shiny.
I found a shiny Wooloo after 50 encounters so at least that was good.
No shiny legendarys in den raids, but did get a shiny Shiinotic, Bewear and a G-Max Sandaconda.
