Which came first...

Who cares about the chicken or the egg argument when you've got an Eggling ready to hatch at your discretion! You won't find yolk or gooey membrane, though; beneath this unimpressive shell you will find... dirt. Yes, dirt. Everything you need to start growing a small plant comes inside the egg! Included is also an extra seed packet for the plant in an egg, so the only effort you need to expend comes from choosing between Basil, Lavender, Mint, Petunia, Prickly Cactus, Shasta Daisy, Spicy Red Pepper, or Wild Strawberry. What comes first, then, the Eggling or the egg?
