A hen will sometimes produce double-yolk eggs at the very beginning or near the end of her reproductive life due to hormonal changes. When this happens, the shell forms around two yolks instead of one, creating a double-yolk egg. Double-yolk eggs are safe to eat and cook with. If substituting them for large classic eggs in a recipe, their additional volume may affect the outcome of the recipe.

The hen's reproductive system isn't yet matured, and the chicken sometimes produces two cells at the same time, that are formed into one shell.

It is a dizygotic egg, which means that it had two zygotes in it. Basically, it was twins.
