I broke an egg & it had TWO yolks. Has this happened to anyone else & what causes it?

Question

"I broke an egg the other day to make scrambled eggs and it had TWO yolks. I've never seen this before. Has this happened to anyone else and what causes it?"

Answer 1

You cracked your first double yolker, lovely aren't they!!
That double yolker would have been twins, Daniel and Damion!

Some hens will lay double-yolked eggs as the result of unsynchronized production cycles. Although heredity causes some hens to have a higher propensity to lay double-yolked eggs, these occur more frequently as occasional abnormalities in young hens beginning to lay. Usually a double-yolked egg will be longer and thinner than an ordinary single-yolk egg. Double-yolked eggs occur rarely, and will only lead to the successful development of two embryos with human intervention

It is also possible for a young hen to produce an egg with no yolk at all. Yolkless eggs are usually formed about a bit of tissue that is sloughed off the ovary or oviduct. This tissue stimulates the secreting glands of the oviduct and a yolkless egg results.

Answer 2

Fantasic! I once had an egg that had 8 yolks in it...yes, 8 yolks but that was because I had the most boring job in the world, I was an egg classifier!!!! It was my weekend job when I was at school and I would classify into sizes, clean and wash over 3000 eggs per day and the only brucie bonus was being able to take the very large eggs that could not be sent to the shops home. We had a fantastic omelette that day :-)

Answer 3

Yes, it can happen, it would have been twin chicks. It's the same idea as human twins, the original fertilised egg divides. It's supposed to be lucky.
Just before my first baby was born, I bought free range eggs I'd bought from a local market; everyegg in the tray - and I'd bought two dozen - had a twin yolk!!

Answer 4

this is actually a common thing to happen. 3-5% of eggs have double yokes.


The formation of a double yolked egg occurs when two mature oocytes are packaged in the same egg.

This is basically the same process that occurs with fraternal twins in mammals.

Answer 5

When two ova are released from the ovary at the same time instead of the normal single one,both pass together through the reproductive tract & get enveloped together in a single shell,such eggs are not uncommon.If incubted these never hatch as twins

Answer 6

Yes- it is not uncommon, but the breeds that are used for commercial egg laying are less likely to produce double yolkers- and even if they do, they are usually rejected when they go through the grading machine, that is why you see them so rearly. I used to have Black Rock hens(not used in batteries) and they often layed double- sometimes tripple yolkers. As for the cause- I don't really know- because they could never develop properly in to a chick- so I suppose it is a defect really.

Answer 7

Yes many times. My mother is a baker and i've seen many like that. Once she even cracked an egg open and found a whole other little egg inside, shell and all.
I heard once that this sometimes happens to chickens that lay for the first time.

Answer 8

Lots. I once bought half a dozen eggs, four of them had two yolks, one only had one, and the last one had three. As a child we kept chickens and it was not uncommon to have double yolkers and the occasional three.

Answer 9

yea twins chickens, the yolk off the egg is the same thing as the period which woman get

Answer 10

Yep. Without being too flippant, twin chickens. Just like with people, two fertilizable yolks result in twin birth if taken that far.
