If there are two yolks in an egg..?

I have never seen such a thing till now are you serious about it?

no way man.....that's not possible...yolk is just food for the embryo which appears as the white fluid....

maybe who knows this could be something like having twin babies so is there a way of knowing for sure,

In a sat-on-and-hatched-by-mum egg, the chicken has to rotate around, so it gets its head up to where the air cell is. Then, under normal circumstances, the baby chicken will peck its way out. But if there are two chickens inside, they will almost invariably fight each other. Neither of them will be able to get to the air cell, so they both die. However, there have been a few very rare cases where the egg has been very carefully opened at exactly the right time (in a kind of mini-Caesarian), and two chickens have survived from a double-yolked egg. It's rare, but it happens.

Normally only one is fertilized so only one would be hatched. But if both are fertilized, one would be stronger and the weaker would die and be reabsorbed.

Hey! Wouldn't that make it twins? Its quite cute to find an egg having 2 yolks. So far, I have been eating so many eggs and I never see such things. You're lucky!
