Actually, according to Wikipedia, there is such thing. It is rare and is considered to be abnormal just as double yolk eggs are.
Here is a direct quote from Wikipedia: "...It is also possible for a young hen to produce an egg with no yolk at all. Yolkless eggs are usually formed about a bit of tissue that is sloughed off the ovary or oviduct. This tissue stimulates the secreting glands of the oviduct and a yolkless egg results."
