Can ducks fly?

Domestic ducks have certain flying ability, but they can't fly high or far. Wing degeneration is one of the reasons, and more importantly, weight gain. The average weight of domestic ducks exceeds that of large birds such as swans and bustards.

This is related to the evolution of living things. I used to raise a lot of poultry (including chickens, ducks and geese). After human ancestors caught these things that used to fly in the sky, some were still alive, and some were temporarily inedible.

Keep them in captivity, and over time, these things will be handed down from generation to generation, and slowly they will not fly. The ducks are artificially bred by wild ducks. After being raised by humans, the flying ability decreased.

Floating reason

Duck's tail has a large fat gland called caudate fat gland. Its chest can also secrete a kind of "powder"-like horny flake, which contains fat. Usually, I often peck with my mouth, rubbing the fat secreted by the fat glands at the tail and the "powdery" horny flakes secreted by the chest hair onto the feathers.

Therefore, when it enters the water, its feathers will not touch the water. At the same time, its feathers are very light and can be lifted by water and float on the water. Besides, geese and waterfowl are just like ducks. Although chickens also have fat, the amount is very small, so they can't float in the water.
