There are a couple reasons why you will find double yolkers. All most all reasons (genetics, illness, surprise, accident) will have the same effect, the hens ovaries release 2 or more yolks instead of the usually 1 at a time .

∙ 10y agoYes, it happens but not very often. Chances are embryo's will die well before they hatch.
Large hatcheries do not even bother when they candle and see two yolks.
The first obstacle is the chance that both yolks are fertilized, one or the other may be but two would be rare. One developing chick in with a non viable yolk is not good either. If by chance both were viable then it is a matter of space. As they develop, quarters get cramped rather quickly. Then there is the air problem. When the single chick first pips, one of the things it gets is air, nice fresh air. It has been living on the air stored in the egg between membranes. Two chicks working hard, use that small amount of air up very quick. Egg shells are porous but two chicks competing for the same air as one would normally need is another obstacle, so they must be fast and break through the two membranes and the shell at record speed.
All this adds up to, if it happens, both chicks and you have been very lucky, two for one deals are rare in the bird hatching game.

I wouldn't even bother trying to hatch a double yolker. The embryos will develop to a point and then there isn't enough room or nutrients to finish developing normally. It will just stink when you finally remove it from the incubator or nest.
The problem is the yolk is the food for the growing embryo (no umbilical) in a fertilized egg. The shell is the (womb) so to speak. While the shell is somewhat porous (allowing some air) it does not allow for expansion as the two embryos develop. No way to expand and limited moisture for lubrication spells disaster. The last few days of development are crucial and when those little lungs first expand they use up much of what air is in the shell rather rapidly. Double yolk eggs are rather sad when hatch is attempted. The chicks will often develop to the point of peeping or trying to open the shell but because resources have been depleted neither chick has enough room or lubrication to move about much and often neither can make that first essential opening thus letting in that much needed air.

Wiki User
∙ 14y agoNo. Not naturally but it can be done (rarely) when developed out of the shell.
Fertilized double yolk eggs do not produce twins as the restrictive interior of the shell will not support the needs of two fully developed chicks.
Wiki User
∙ 15y agoany! Because i have two types of chickens in the roost with a rooster and i get some eggs that are double yolkers!

∙ 11y agoNot any particular breed. It is like twins, and just happens every now and then.

If a chicken lays a double yolked egg and its fertilized what position do the baby chicks have to use to stay alive?
The small end of the egg should be placed down at all times. When advised to turn eggs during artificial incubation, the turn needs only to be 90 degrees from one side to the other. The egg should not be turned from end to end. Mother hens naturally just roll the egg from one side of the nest to the other, they do not stand the eggs upright. Now about the double yolked egg. It is unlikely that the egg will incubate to hatch. Most novice breeders get all excited when they candle a double yolked egg thinking they will get twin chicks but they are always disappointed. It happens very seldom. The two yolk eggs, while they will usually develop to about day 16 of the 21 day cycle will often end in the death of both developing chicks. This is because the egg shell is not well suited to sustaining twin embryos. The reason you keep the large end of the egg up for 21 days is so air will collect in the top of the shell as moisture evaporates. This air is used to sustain the chick just prior to "peeping" or getting out of the shell. Two viable chicks in the same shell use double the amount of air and will often suffocate prior to opening that all important first hole and allowing air into the shell while they continue to break out. Movement inside the shell is also important in those last few days and two chicks occupying the space restricts that much more than a normal single chick in an egg.
Is a double yolk in an egg good luck?
Only to the superstitious. Double-yolk eggs occur when ovulation occurs too rapidly, or when one yolk becomes joined with another yolk. These eggs may be the result of a young hen's productive cycle not yet being harmonized. BUT yes people do say Its Good Luck or you may get a twin if someone is pregnant. :)
Why do other eggs have two egg yolks?
Eggs with a double yolk are not that uncommon. A double yolk results from two ovum dropping from a ruptured follicle. In some cases, two follicles rupture at the same time and a double yolked egg is produced. Some hens do this on a consistent basis and are often bred for this genetic trait. Double yolk eggs can be purchased in many major supermarkets. The Guinness Book of World Records reports a 9 yolk egg was once found. Here on my farm I have had eggs with 4 yolks.
What dog was in white chicks?
that is easy pit bullITS APOMERANIAN if your talking about the twin sisters pet). And then the Latreals dog is a Rottweiler.The small fluffy dog with a lion cut that hung out with the sisters is aPomeranian and the guard dog was a rottweiler. However, they are NOT real dogs, but very realistic computerized models.
Did Ernest Shackleton have a twin?
No he only had brothers and sisters, no twin
Can double yoke eggs produce twins?
While double yolks can produce two chicks it will often cause problem because they are competing for nutrents and space within the shell. I have had twin bantam chicks hatch from what was obviously a double yolked egg. Fraternal twins, one cock and one hen.

What is the difference between double room and twin room in hotels?
A double room has one double bed. A twin room has two twin beds.
What is the difference between a twin and double hotel room?
A twin bedroom has two single beds, a double bedroom has a double bed!
What is the difference between a double mattress and twin mattress?
A twin is made for one person and a double is made for two. A double is the same as a full...just different name. A twin is also known as a single (twin=single, full=double). I think they should have just stuck with a single and double...much easier to keep straight. A twin is for one person, really? How confusing!As a side note, 2 Twin/Single XL's (4 inches longer) are equivalent to a King.
What is bigger bed Bigger twin or double?
double is bigger.
Are twin and full matresses the same size?
No - A twin is the same as a single. The full is the same as a double. Twin < Full
Are poppi monroe and Annie mcelwain sisters in real life?
No, they are not related. They played twin sisters in the movie "Double Teamed".
Will a double mattress fit on a twin frame?
Mattress sizes are notoriously confusing, but in general, a "double" is significantly wider (as in, over a foot wider) than a twin and will not fit on a twin frame.
