Windurst Culinarian's Guild will sell these if someone has crafted them and sold them back to the guild.
They're listed on Siren Jeuno AH for 4k a stack, but I didn't have much selling them there, or Bazaar'ing them at 2.5k a stack either.
I had some good skill-ups making them, but will definitely come off at a loss.
It's also worth noting that although a had good skill-ups with lizard eggs to 47, after I switched to bird eggs, the skill-ups were noticeably worse. I kept going to use up my ingredients, but in retrospect, I should've sold off the stuff and gone to something else.
Moral of the story- these are good for getting cooking from 43-47, but not so good for 47-49.
