I think that is possible to know if a egg have a shiny inside

[SercaK]

This is a teory that i made when i was hatching some boxes on my egg hunt. When do you search for the ivs on the pc, you are able to know if a egg have that iv:

Having this on mind, if do you search on the same tool your shinies, i think that you be able to know if  any egg have a shiny inside:

Its possible to test this. If someone actualy is doing a shiny breed, put the egg on box and try to search your shinies, if happen the same thing that happen on ivs .. Well the title of this topic is self explanatory ;D .

The individual of the egg is inherited from the parent and does not have a vein of 31 just because he is a flash

It doesn't confirm shiny before it hatches, just like it doesn't predict gender as an egg

There used to be a bug where you could search "Shiny" in the PC and it would identify if an egg was holding a shiny pokemon, but this is no longer the case. You will have to wait, and there's no way around that.

@SercaK I heard that if you shiny breed (with particles), if any of the eggs doesn't shows the particle sign in box, that is a shiny egg (tbc though)

I wonder how many people have boxes of eggs, gotten the shiny they're looking for, then continued hatching what they already had and got another one.
