Eggs are among the major source of affordable protein needed by humans.
Double-yolk, yolkless and red yolk eggs are all forms of egg abnormalities.
Most of us eat egg but it is very seldom that we encounter abnormal eggs such as double-yolk, yolkless and red yolk eggs. In my lifetime, I had only encounter double-yolk egg twice. The first one was when I am still in elementary and the second was last week. I had seen a yolkless egg once and I don’t remember seeing a red yolk egg.
One of the most unusual forms of egg is the double-yolk egg. There are several reasons for the occurrence of double-yolk eggs:
- it occurs when ovulation occurs too rapidly
- it occurs when one yolk becomes joined with another yolk
- it may be the result of a young hen’s productive cycle not yet being synchronized
- hybrid breeds of hens also produce double yolk eggs by default.
- some hens will rarely lay double-yolk eggs as the result of unsynchronized production cycles.
A double-yolk egg is usually longer and thinner than an ordinary single-yolk egg. Double-yolk eggs usually only lead to observed successful hatchlings under human intervention, as the chickens interfere with each other’s hatching process and die
The second form of egg abnormality is the red yolk egg. This kind of egg has an extremely thick red yolk.
The third form of egg abnormality is the yolkless egg. An egg without a yolk is called "dwarf" or "wind" egg. This kind of egg since it contained no yolk and therefore can’t hatch.
