People love egg sitting....emu eggs. Not so much chickens or quail. The novelty of "emus", will lure in unsuspecting friends and family. For just 4 eggs you should be able rig something up in a 0maha steak cooler. Totally portable. Just a suggestion as my understanding auto turners for emus don't exist.Unfortunately I travel for work and I am sometimes away for a few days at a time so hand turning is not an option.
