Used for the Artisan Cooking quest, and for Monster Omelets, these eggs always seem to go for good gold on the AH. You can get them all over the place, but I found Deadwind Pass to be the easiest. The birds there drop them at a very high rate, and drop some other nice gray items, too (including Vibrant Plumes used for Darkmoon rep). I mention Winterspring because the Ragged Owlbeasts there have a fabulous drop rate for them…but they’re more spread out and mixed in with other mobs. Deadwind Pass is just a loop where you kill a bird, then another, etc. until you’re back where you started. You can also run loops as a level 70 waiting for you Karazhan group to arrive. I’ve also heard rumors that they drop from the vultures in Westfall, just by the cemetery near Moonbrook, and that the respawn rate there is insane. If that’s true, that would be a farmer’s dream.
