I took a video of my whispering egg harvesting method.



However, this is now the old method as I'm an idiot and there is an even faster method. Put a wall around ONE nest of eggs, usually around 8 walls built up against the building to surround it. Then harvest an egg INSIDE that wall, then jetpack out. Congratulations! Those assholes are now all trapped inside a wooden prison and you're free to run around and harvest every single other egg on the ground.
