Cracking open an egg and finding not one but two yolks is like hitting the breakfast jackpot. But it’s also a little suspicious. Why is it happening? What does it mean? What do you do with such an anomaly? We have all of those answers and more. Here, everything you need to know about double-yolk eggs.
What are the odds of getting a double yolk? Without any outside interference, the odds of getting a double-yolker are about one in every thousand eggs.
Why do double yolks happen? Double-yolk eggs are a byproduct of rapid ovulation. That means two yolks are released in quick succession into a hen’s oviduct (aka Fallopian tube) and end up in the same shell. Typically, yolks are released about an hour apart, but hormonal changes or a hyperactive ovary will cause double releases.
