User blog:HeißerHans/Is the Shiny mechanism broken?

Hi, I really need help! I am making a challenge; im only allowed to play through the game with shiny pokémon. I already have a shiny starter salatad and two shiny hamstars. My problem: i have been playing for many hours now, not finding a single shiny. Im already at 445 re's. Whats wrong? am i just having really bad luck?
