An easier way to get shinies?

Question

So, I was wondering, if there was an easier way to get shinies in X and Y than chain fishing and the pokeradar. I know that if you breed two Pokemon from two different countries, the chances go up 6x. Well, what if you were to get 2 shiny, say, magicarp (since those are kinda the most common shinies) that were from two different countries and breed them. Would the chances to get a shiny increase even more than six times?

What do you mean different countries?

Answer 1

I don't think so.
Other than those three you mentioned, there is no other way.

Answer 2

No. Breeding two shiny Pokemon will not increase the chances of getting shiny offspring.
