Eating fried chicken every day, 10 interesting knowledge about chicken! How many do you know?

About 8000 years ago, chickens began to be domesticated in southern China and gradually expanded globally over the next few thousand years.

Afterwards, chicken and eggs became important sources of protein for humans.

Nowadays, there are over 30 billion domestic chickens worldwide, and the United States alone consumes about 8 billion chickens annually.

Here are 10 interesting cold knowledge about chickens that can help us gain a more comprehensive understanding of this animal:

1. * * Chickens can dream: * * Studies have shown that chickens also experience rapid eye movement sleep while sleeping, which means they may also dream.

In addition, chickens have a sleep pattern that humans do not have, called single brain slow wave sleep, which allows the brain to continuously monitor changes in the surrounding environment during sleep.

2. * * Chicken's Vision: * * Chicken's vision surpasses that of humans, as they can see three colors: red, green, and blue, as well as ultraviolet rays.

This is attributed to the presence of five types of photoreceptors in the corns, allowing them to see more colors and observe sunrise earlier than humans.

3. * * Chicken rolling in the soil: * * The behavior of chickens rolling in the soil is to clean the spoiled oil on their backs.

There is an oil gland on the back of the chicken, which is used to coat feathers to maintain waterproofing, but the oil will spoil over time, so the chicken will use soil to clean the oil on its body.

4. * * Egg color and hen's earlobes: * * The color of the hen's earlobes can be inferred from the color of the eggs. For example, brown eggs usually correspond to red earlobes, while white eggs correspond to white earlobes.

5. * * Chickens are omnivores: * * Chickens are not vegan animals. They eat small animals such as insects, frogs, and even mice because these foods provide higher energy.

6. Taste of * * Chickens: * * Chickens have relatively fewer taste buds, mostly located at the back of their mouths, which prevents them from tasting sweet flavors, but can still taste salty ones.

In addition, roosters have more taste buds than hens, while broilers have more taste buds than laying hens.

7. * * The Greatest Egg: * * There is a record of 371 eggs laid by chickens in a year, and the maximum weight of double yolk eggs is 340 grams.

Double yolk eggs are usually caused by the more active reproductive system of hens, but they do not hatch two chicks.

8. Social structure of chickens: Chickens are social animals that confirm their social status through fighting and determine their pecking order based on their status.

9. * * Chicken beak sensitivity: * * Chicken beaks have high sensitivity, similar to human hands, and can be used to explore, drink water, comb hair, and defend.

10. * * Chickens can swim: * * Chickens can swim in water, although their buoyancy is poor and they are also prone to fatigue. Especially for chicks, due to incomplete feather development, they are more at risk of drowning.

These interesting facts help us better understand the animals that often appear in our lives.
