Most of us don’t imagine an egg shell as having holes in it, but there are as many as 17,000 tiny pores on an egg shell. As the egg ages, these tiny holes permit moisture and carbon dioxide to move out and air to move in to form the air cell.
Do chickens have 1 or 2 holes?
Unlike humans and most mammals, a female chicken has but one rear orifice with three functions. It is where feces and eggs exit her body and sperm enter. The rooster’s cloaca has only two functions. One is to pass feces.
How many pores an egg shell have?
Looking at the egg from the outside we see the shell, which is a hard, protective covering composed primarily of calcium carbonate. The shell is porous and the large end contains more pores than the small end of the egg. (There are about 7,000 pores in a chicken eggshell.)

One. The egg, poop, and urine (which for a chicken isn’t a liquid) exits out of the same hole called the cloaca and ends in the vent.
Do all eggs have holes?
Hitchcock was wrong about one thing: Eggs do have holes. A single eggshell is perforated by 9,000 pores, on average.

Roosters have reproductive organs not unlike mammals, with testes that produce sperm. The sperm travel down tubes called vas deferens to sperm sacs.
Are hens asexual?
As with most bird species, roosters and hens don’t have external genitalia. Instead both partners procreate using an external orifice called a cloaca. When the cloacae are touched together, sperm is transferred into the female reproductive tract.

What animal makes a hole in eggs?
Missing or Damaged Eggs
A skunk punches a hole into an egg, then sticks its muzzle in to lick out the contents. Raccoons and opossums tend to crush eggs to eat them, leaving behind a mess of mashed shell and oozing interiors.
Do chickens menstruate?
Although chickens do not menstruate (and thus their eggs are not “chicken periods” as is sometimes asserted), the cycle of creating and passing much larger eggs relative to their body size and weight is arguably even more physically taxing, especially in modern hens who have been bred to produce such unnaturally high
Can you eat a fertilized egg?

How full is an egg?
When the egg is freshly laid, the shell is completely filled. The air cell is formed by contraction of the contents during cooling and by the loss of moisture. A high-quality egg has only a small air cell. The yolk is well-centered in the albumen and is surrounded by the vitelline membrane, which is colorless.
