Arkadu: Shiny Egg, ie nature/ability/gender/shininess is on a different frame counter. To advance that, read this from the first page:
Hatching for shiny Eggs\Eggs of a certain nature
Unlike DPPt, HGSS does not have the benefit of coin flips and happiness taps, which were used to skip through eggs until one of the desired nature and\or shininess is found. In HGSS, eggs must be received\rejected from the Day-Care Man one at a time until the desired egg is reached. RNG Reporter (link in signature) has an option to search for very low egg PID frames, making it possible to find a shiny egg on the very first.
Alternatively, you can also call Joey I hear, but I've never done that.
For IVs, you don't call elm the full listed amount to verify. You call until you're -1 from your target and interact with the old man.
