The thing is, what people don't get is, this is Probability. Every single egg people hatch has 1/4 of a percent chance of being shiny. That's .25 %. People see the 1/456 and think that means that 1 of 456 eggs will be shiny. This is wrong. What it actually means is, for every chance there is for your egg to be shiny there are 455 chances that it will not be. You can have great luck and hatch 3 shinys in a row or you can have a streak of bad luck and get 2000 eggs with no shiny. As long as you keep trying, you will EVENTUALLY get a shiny.
