crack the egg and see if there's two! :P also you can usually judge by the size of the egg (if it's absolutely enormous) then it's most likely a double yolker. it's not 100 percent accurate until you open it up :)
No, but some people breed specifically for chickens that lay double yolks.
Double yolks are not that rare. Double yolks are a result of two ovum being released to the hens oviduct at the same time.
No, not all extra large eggs have two yolks. While double yolks can occur in larger eggs due to the hen's reproductive cycle, they are relatively rare. Most extra large eggs typically contain a single yolk. The occurrence of double yolks is more of an anomaly than a standard characteristic of extra large eggs.
TWO YOLKS INSTEAD OF ONE ARE FOUND IN SIDE THE EGG
The world record for the largest number of yolks found in one egg is 9, as verified by the Guinness World Records. Multi-yolked eggs, also known as double-yolkers, are relatively rare occurrences caused by the hen releasing two yolks in quick succession.
Double yolk eggs are formed when a hen releases two yolks into the same eggshell. This can happen due to a hen's reproductive system being stimulated to release two yolks at once, or because of a genetic predisposition in certain breeds of hens.
No, but I have seen them outside the egg, after it was cracked. Double-yolked eggs are not uncommon.
The record for multiple egg yolks in one egg is nine. Guinness Book of Records lists the world's largest chicken egg as having a diameter of 9 inches and contained 5 yolks. The heaviest egg at 1 pound (normal is 2 - 2.5 ounces) had a double yolk and double shell.
yolks - like egg yolks
Yes! The yolks have nutrition and energy for you.
A double yolk is formed when the hen releases two ova from the follicle. Both yolks are enclosed in a single shell over the 24 hours of egg formation.
Many birds can lay a double yolk egg. Chickens,ducks and turkeys all will occasionally lay a double yolk egg. Double yolk eggs will not hatch.
