Rare Chicken Egg Hides Another Egg Inside

Chicken eggs have long been included in the daily diet of humans and so many other animals (sorry eggs, you seem to be at the bottom of the food chain). However, when something goes wrong in a chicken's reproductive system, as in other animals, there are deviations to be expected in the embryonic period, in other words, your breakfast egg will look a bit odd. Take a look at the egg that contains another egg inside it! Watch the video at the top of the page.

Texas farmer Gary noticed a strange phenomenon with one of his chickens from the farm. His seven-month-old chicken named Gertrude started laying very large eggs with another egg inside them. Despite the strange occurrence, Gertrude does not seem to have been harmed and the egg yolks have a normal taste.

How is this possible? The incubation of one egg inside another is not a miracle of nature and is definitely not a trick, but simply a very rare natural phenomenon. The technical term for it sounds too scientific for a morning read, but here we go: reduction of counter-peristalsis contraction. The bottom line is that one egg, which has not yet fully formed in the reproductive mechanism of the chicken, returns back to the box, and the second is formed around it.

This phenomenon, however unusual, isn’t all that rare really. A housewife got the shock of her life when she cracked open a huge egg to find a smaller egg inside - perfectly intact. Maria Glória de Souza collected the gigantic egg from the chicken coop in the backyard of her house in Catalao, central Brazil, after it was laid by one of her hens. The ginormous offering was triple the size of a normal egg, weighing in at 6.5 ounces. The phenomenon is called a counter-peristalsis contraction and occurs while the hen is in the process of forming an egg, where a second yolk is being released before the first egg forms completely.

Under normal circumstances, the hen ovulates and releases an ovum that passes through the 5 sections of the oviduct, along the way forming protein, auxiliary elements and finally a shell that keeps everything together and protects the contents from outside influences. Sometimes at some stage, a failure occurs, and then the half-formed egg does not leave the chicken, but the new one starts to form directly on top of it.

This counter-peristalsis contraction, resulting from the premature release of a second egg cell into the oviduct, causes the first egg in the eggshell gland to reverse its course and be pushed back up to the top of the oviduct and then added to the egg cell that was just released into the oviduct.

In the end, a very large egg can hardly be pushed through the cloaca. This phenomenon should not be confused with another, much more frequent, when the formation of two eggs instead of one leads to the fact that the egg has two yolks.
