Shiny Pokemon Week Day 5

Today, I played Pokémon Omega Ruby for at least four hours today and I am still having bad luck in getting a shiny. Almost 680 eggs hatched and no shiny. Given the odds of getting a shiny through the Masuda method (1/683), there was a good chance that one of the 680 Pokémon hatched should have been a shiny. Even if more than 683 eggs were hatched, there was no guarantee that at least one of the Pokémon hatched would have been a shiny. Even if it takes more than a week, I am still hatching eggs from the same parents the non shiny Pokémon came from until I get a shiny Pokémon.
