Doduo, the twin bird Pokémon from Kanto, can be found in the wild in Pokémon Go. Yes, Doduo can be shiny in Pokémon Go!

Doduo and its big sibling Dodrio are fuzzy and neat, but they don’t see much meta relevance at all. If you’re still missing these from your Pokédex, you’ll want to nab them, but otherwise they have no use. :( Sad.
What is the shiny rate for Doduo in Pokémon Go?
As per old research by the now-defunct website The Silph Road (via Wayback Machine), the shiny rate for Pokémon on a regular day is approximately one in 500. Doduo is not a Pokémon that gets a “permaboost” (meaning that it’s a rare spawn and thus gets a boosted shiny rate).
Not much, unfortunately. It appears to be random chance. Shiny Pokémon catch rates are set by developer Niantic, and they are typically only boosted during special events like Community Days or Safari Zones, or in Legendary Raids. There are no consumable items that boost shiny Pokémon rates.
LeekDuck keeps a list of currently available shiny Pokémon. It’s a helpful visual guide that illustrates what all of the existing shiny Pokémon look like.
