Today’s quick and dirty guide – You Can’t Make a Giant Omlette. Now that Draenor flying is available this achievement is arguably one of the easiest in the game.
Short version, fly to the birds nest shown in the video and click the egg. If the egg isn’t there just wait for it to respawn (it’s on a short respawn timer – around 5 minutes).
The only other requirement is that you’re on the Garrison daily quest “Assault on Darktide Roost”. Congrats on 10 more nerd points!
