We can find a lot of oddities and abnormalities in the animal kingdom: here’s a list that you should know well before you think you’ve ended up in some sci-fi movie.
1.Eggs with tails.
This is likely caused by a hen trying to pass her soft-shelled egg and, in the process, the end portion of the egg got stuck and remained inside of the vent.
2. Soft-shelled eggs.
These eggs, unlike the shell-less eggs, in fact have a shell that contains yolk and albumen, but it is soft. It can occur in very old or very young hens. It can also happen when a hen is stressed or has a calcium or vitamin D deficiency.
3. Speckled eggs.
These small speckles can be caused by an excess of calcium. They also depend on the size and structure of the animal.
4. Odd shaped eggs.
Soft-shelled odd-shaped eggs: it can occur when there’s some sort of abnormal disturbance in the egg forming process.
5. Green or blue eggs.
There are three breeds that lay blue eggs: Ameraucanas, Araucanas and Cream Legbars. Green egg-layers are created by cross breeding a blue-egg-laying breed and a brown-egg-laying breed.
6. Very small eggs.
Lovingly referred to as fart eggs, rooster eggs or fairy eggs, very small eggs typically are missing the yolk.
7. Egg within an egg.
It occurs when a hen releases a second egg into the oviduct before the first egg has completed the laying process.
8. Multiple yolk eggs.
This is a rare thing and is an oddity when it comes to eggs that are not intended to be eaten. It is impossible for more than one chick to develop within a single egg.
9. Body-checked eggs.
“Wrinkled” eggs are more commonly seen in older hens suffering from airborne disease.
10. Incomplete pigmentation.
According to Florida University research, contributing factors to this condition include stress and old age.
11. Round eggs.
A British woman sold a round egg for over $600: if you find it you could get rich.
