Can the Orochick (Wondrous Egg) be acquired? If so, how?

Update: A dev got back to me with this:

So I passed everything on to our dev folk for investigation, I can confirm for you that no one has ever gotten the wondrous egg. My only guess can be that folks may have gotten it mixed up with the other egg (an easy mixup for sure). I also fear that the information you received from our CS agents appears to be incorrect, at least as far as we can tell, no one has ever gotten the egg nor has it been distributed in-game.

THANK YOU FOR ASKING THIS. I posted the first sourced link so I'll just add that BioWare themselves said it was ingame when they mentioned how it could now be sold on the GTN in Patch Notes 1.2.2.

As for the egg--yeah, there's been A LOT of rumors without any proof. The most spread around one is that it drops from HM Kephess, but there has been absolutely no proof at all.

Other rumors are that it drops from Kephess anywhere in EC, that it just drops in EC (but from what is unknown), and that after you defeat Kephess (no difficulty specified), a nest spawns somewhere in the instance and an egg spawns in it. I've been all of the instance so I doubt it but bleh.
