Pokémon Go Developer Declines to Confirm Hidden Nerf to Wild Shiny Odds as Part of New Season Changes - IGN
Players of Pokémon Go have observed that shiny Pokémon odds in the wild may have been secretly reduced as part of new season changes, making rare variants harder to find. Niantic, the developer, declined to comment on specific shiny rates, citing policy. While Niantic advertised increased shiny chances for Pokémon in eggs and raids, and for evolved forms in the wild, player-sourced data suggests a general flattening of odds from previously boosted rates for certain species.
