Like omg!
This is what I found when I started to make me an omlette this morning. The egg was pretty big in size compared to the others...and I found out why after I cracked this babie(s) open. I guess it's pretty rare. I ate it nonetheless. =) Twas good. Yeah.
I did some research and a farming site states that
"Double-yolkers occur when ovulation happens too rapidly, or when a yolk gets lost and is joined by the next one in line. They’re most often laid by pullets just beginning to synchronize their laying pattern, and some heavy-breed hens carry this tendency as an inherited trait. Rarely, an egg contains more than two yolks the world record is nine yolks in one egg."
Some cultures claim its extremely bad luck, claiming that it could lead to a death or injury in the family whereas some claim that it's extremely good luck, for someone might be pregnant. I hope to remain unaffected by both. I just dig the fact that it happens to one in every 10,000 eggs laid.
Hmm...rare after all. :)
