Shiny Pokemon Week Day 4

Today, I played Pokémon Omega Ruby for over three hours and my total hatched egg count from the start of this challenge is over 530 eggs without a shiny, which beats the record I have for my shiny Skitty, which is 424 eggs by over 100. Maybe I'll be lucky and get a shiny tomorrow or maybe I won't get a shiny throughout this week at all. At least I tried if that is the case but I am not stopping until the end of this week. I wanted to give up today because I had no luck but maybe something will happen. I wonder what the nature and gender of the shiny Pokémon will be.
