A chicken’s belly button is located on their lower abdomen, more specifically on their vent which is located near their tail feathers. The vent is a hole located on the chicken’s abdomen where they expel their waste, lay eggs, and occasionally take in air.
A chicken’s vent is often mistaken for their belly button by untrained observers because at a glance, the color of the feathers around the vent area is similar to the color of a standard belly button.
However, this is not the same as a human’s belly button as chickens do not have an umbilical cord.

Does a chicken have a umbilical cord?
No, a chicken does not have an umbilical cord. The umbilical cord is part of the reproductive process between mammals. It connects the mother to her offspring and carries essential nutrients from the mother’s placenta through to the developing fetus.
However, the reproductive process of birds – including chickens – is much different than mammals. For example, chickens lay eggs and those eggs contain the necessary nutrients the newly-hatched chick needs in order to develop.
Therefore, chickens do not have an umbilical cord.
Do girl chickens get periods?
No, girl chickens do not get periods. Chickens do not have menstrual cycles or periods like humans or some other animals like cats and dogs do. Chickens (and other birds) are oviparous animals, which means they lay eggs.
Every egg that a chicken lays has the potential to become a chicken if given the right conditions for incubation. This is what enables the chicken species to reproduce and keep their population going.
What animals have no umbilical cords?
Animals such as birds, fish, and certain invertebrates do not have umbilical cords. Reptiles, although they have an embryonic stage, do not have umbilical cords, because they exchange gases and nutrients through their skin.
Adult amphibians, such as frogs and salamanders, do not have umbilical cords either. Furthermore, adult mammals do not have umbilical cords. In mammals, the umbilical cord is a special part of the placenta, which only serves during fetal development to connect the fetus to the mother, allowing for the exchange of gases, nutrients and waste products between the mother and the developing fetus.
After a mammal is born, the umbilical cord no longer serves its purpose and eventually disintegrates.
Is it true that animals that lay eggs don’t have belly buttons?
No, it is not true that all animals that lay eggs don’t have belly buttons. While some egg-laying species such as fish, amphibians, reptiles, and birds do not typically have a visible belly button, many other species of egg-laying animals do have a belly button.
These animals include mammals such as opossums and kangaroos, as well as bird species such as ducks, chickens, and geese. The reason that these types of animals have a visible belly button is because after the egg hatches from the mother’s body, the egg still needs some nutrients in order to continue developing.
These nutrients are absorbed by the umbilical cord, which attaches the fetus to the mother, and the belly button is where the umbilical cord attaches. Therefore, the belly button serves an important function for the growing fetus and many egg-laying animals still have a visible belly button.
What is the only animal that can turn its stomach inside out?
The only animal that can turn its stomach inside out is the flounder. This species of fish, found in shallow temperate waters around the world, is able to turn its stomach inside out when under attack from a predator.
This is achieved by the flounder using strong muscles to rotate its stomach so that the prey can be ejected. A study in 2011 found that the physical process of turning their stomachs takes just fractions of a second and the escape mechanism occurs when the flounder faces an attack from the side.
Flounders also have unique eyes that can be rotated independently of each other to give them a wide field of vision as they lie on the ocean floor.
How do monkeys cut the umbilical cord?
Monkeys do not cut their own umbilical cord. Generally, their mother will either bite the cord, chew it or simply break it with her hands. Monkeys use their upper and lower canines to bite and tear the umbilical cord of their new baby, and their incisors to chew and break it.
The umbilical cord is a tough fibrous material and requires a lot of force to break and separate it, so it is important for the mother to be careful when biting and tearing the cord. Once the umbilical cord has been cut, the baby monkey is typically licked and cleaned by their mother, and the mother may even eat the placenta.
The umbilical cord is typically disposed of and is a source of nutrition for the newborn monkey.
