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 .
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.
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. :)
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.
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.
No he only had brothers and sisters, no twin
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.
Tell the Girl twin to put out. Fat Chicks always do more stuff

A double room has one double bed. A twin room has two twin beds.
A twin bedroom has two single beds, a double bedroom has a double bed!
double is bigger.
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.
No - A twin is the same as a single. The full is the same as a double. Twin < Full
No, they are not related. They played twin sisters in the movie "Double Teamed".
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.
there are different mixes to make them I happen to know a few so here they are Green-fin spotanus = you get this when you hatch the eggs at the begaining speckaled leaffish = Twin-Fin beta and orange stickfish crimson comet = Twin-Fin beta and hornet goldshark (There is more mixes to get these fish)
