Ditto and pokemon eggs

I have been recently told by some of my friends that Ditto (the Pokemon, not the word) can copy any Pokemon egg group and have the egg of the different Pokemon.  Normally, you have to have two Pokemon of the same egg group and the Pokemon that hatches out of the egg will be the female's species.  But since Ditto's gender is unknown and it's in a special group with only itself, it can copy to be any egg group as long as the other Pokemon is a female (because it will still inhabit the female's species...p.s., if you put two Dittos in the daycare, I'm guessing that a Ditto egg will hatch).  Every Pokemon except for Legendarys has an egg group so this is an especially helpful tip.  (I have not tested this but I will comment later to tell you if it works).

You can catch Ditto in Crater Forest which is right by the giant chasm, which is right by Route 13, which is right by Lacunosa Town.

Good luck!
