"Eggstra" yolks? Double yolks egg. What a delight as it's not easy to get a double yolk egg.

Why it's so? A double yolk is formed when a chicken releases two yolks into the same shell and it's typically produced by young chickens whose reproductive systems have not fully matured.

Double-yolked eggs are perfectly fine and safe to eat. Some believe it's a sign of good luck to fine them.
