According to traditional folk belief, cracking open an egg with two yolks signifies that someone—often the person who breaks it—will soon conceive twins. In some versions of the superstition, any woman of childbearing age in the household or family is seen as the potential recipient of this dual blessing.
The double yolk, being an unusual natural occurrence, is interpreted as a symbolic parallel to twin pregnancy: two lives developing within a single space. Variations of the belief assign even deeper meaning:
- The freshness or brightness of the yolks may signal the health or gender of the predicted twins.
- The closeness or separation of the yolks may suggest whether the twins will be identical or fraternal.
- Some traditions extend the omen’s meaning to future multiple births in general, beyond twins.
The belief is especially common in farming households where daily egg collection made unusual eggs a source of domestic prophecy. Eggs, as ancient fertility symbols, are often treated as natural mediums for reproductive divination.
