They all have wings, so why do birds fly but chickens can t?

They all have wings, so why do birds fly but chickens can't? This has to do with the weight of the chicken, with being domesticated into a poultry. The definition of flight should not refer to gliding from high altitude to low altitude, but to the ability to fly from low to high places and have the ability to steer freely over a long distance.

I've seen chickens glide over a long distance, from my house to the foot of the hill across the river, in a downward trend the whole time. The chickens are also flapping their wings, but they are powerless to fly upwards; Even the direction can only land in a straight line in the direction of rushing. This has a lot to do with the weight of the chicken, and in the process of the chicken spreading its wings, the force of the wings flapping cannot bear the load brought by its own weight.

Resulting in chickens not being able to fly high.

Once, when I was grazing sheep, I found grass in the mountains.

There was a sound, and I threw a pebble at it, and a pheasant fluttered its wings and flew to the opposite hill, and when I was about to reach it, it turned slightly and flew to the grass in another hill beside me. It was only when I flew away that I realized that pheasants could fly, although I didn't see how high they could fly. This should be because pheasants don't eat much food every day, keep their weight within the range of being able to fly, and have a relatively high vigilance of animals in the wild.

After chickens were domesticated as poultry, they had enough food every day and could be eaten with confidence. As a result, there is no vigilance and the ability to fly is degraded.

Native chickens raised in rural areas have basically no problem getting on trees. Chickens have a strong ability to take off and jump, and they can generally jump up at about meters. This is also the reason why many of the raised chickens will live in trees.

Although he has a strong take-off ability, he still can't fly to high places. But the wings protect the chicken from the risk of jumping and falling.

As domesticated birds, chickens retain their wings, but due to their weight and the degradation of their own abilities during the domestication process, chickens are unable to fly high.

In short, it's okay if you can't fly, after all, chickens are poultry, and if they can fly, then they won't have to eat.

It's because the wings have degenerated, and it's also because of its own heavy size, so it can't fly.

Mainly because although the chicks have wings, they are very obese and can't fly at all.

Because the weight of the bird is generally relatively light, and the wings are relatively large, and the wings of the chick are really small, and they will eventually grow bigger and bigger.

Because the weight of the bird is very light, and the chick is very heavy, and the wings of the chick are very small and cannot fly.

Chicks were originally able to fly, but after being domesticated by humans, they eventually lost the ability to fly, so they could fly within a short distance.

Chickens can actually fly, but they can't fly high, and they can't fly far. But if a chicken wants to fly, it can only flapp its wings in the air a few times or glide down from a high place, and cannot take off on the spot like other birds.

In fact, chickens were able to fly directly in the sky a long, long time ago, but after being raised by humans, they did not need to fly out to hunt by themselves, so after a long time of domestication, the wings of chickens also slowly degenerated, resulting in chickens not being able to fly now. And now the chickens are used to living on the ground, because even on the ground they can easily hunt food, plus humans will feed them, since they are all free of food and clothing, why should they fly?

1.There is a species of parrot called Kakapo, which lives in New Zealand.

Although it is also a parrot, it is the only one that cannot fly, and even if it has wings, it can only jump on the ground. But it is precisely because it cannot fly that this parrot has attracted many predators, so that they are now very scarce, and there are only 126 of them in the world. It is an animal that is on the verge of extinction.

2.The Kan Island duck is also a bird that has wings but cannot fly, and although it has the word "duck" in its name, it is much smaller than a duck. These ducks generally live in swampy areas and are very timid, and can only come out at night.

But they have habits and mandarin ducks.

All the same, it's all monogamy.

Generally, couples live together and do not separate. However, they are also relatively scarce, so they are also critically endangered.

3.The green waterfowl is a bird about the size of a domestic chicken, mainly in Australia, and although it is about the same size as the domestic chicken, its wings are much smaller than that of the domestic chicken. Usually only after encountering natural predators, will they incite their wings to flee, and usually hide their wings under their feathers.

I think it's because the chicken's body is so heavy, and its wings are just empty, so it can't fly.

Chickens can actually fly, but because their wings are particularly hard, they can't fly high or far.

These chickens can't fly until their wings are fully developed, and these chickens can't fly in the first place.

Chickens can fly, but because their wings are particularly hard, they can't fly high or far.

It turns out that before humans raised chickens and ducks as poultry, wild chickens and ducks could fly, flying around the forest in search of food. Later, humans kept them as poultry and locked them up, so they didn't have to fly around on their own in search of food or run away from their enemies. Gradually, pheasants and mallards became obese domestic chickens and ducks, and their ability to fly slowly deteriorated, and their wings gradually lost their ability to fly high.

This long-term habit has changed their flying skills. Chickens, ducks and geese have large bodies and meat, underdeveloped flight feathers, and poor flight ability; Whereas, the bird has a large body and little meat, well-developed flight feathers, and a good ability to fly. So chickens, ducks and geese have wings, but they can't fly freely like birds.

Chickens, ducks and geese can fly, especially in the wild, where wild ducks and geese (i.e. geese) migrate long distances. Domestic chickens, ducks and geese, because they usually fly less, coupled with heavy weight, so the ability to fly is weakened.

Of course, ducks and chicks have wings and can't fly because their bodies are hungry after a long time. For the reason of the plan, they are more suitable on land.

1. The ancestors of this domestic chicken were wild, at that time, they could also fly, since humans raised them as poultry, after training, the wings of chickens degenerated.

2. At the same time, I slowly got used to the living environment on the ground, and over time, the wing musculature retreated, and the body became heavier and heavier. This has been passed down from generation to generation, so chickens nowadays hardly fly.
