Ok guys, here is the video I promised.
I began recording all the egg hatching up until the 12th egg and a shiny Shuckle hatched out.
Enjoy, and good luck!

What game did you try this on?
Well, I'm testing it out on Diamond to see if it will work, using my Japanese Ditto and my Roserade. So far I've hatched 85 eggs, none shiny, but 5 of them got Timid/Modest natures, so I'll probably keep a couple and trade off the rest.
