I keep ducks as home as pets and in winter, I noticed that they become very puffy because they grow something called "duvet" in French (I think it means the same thing in English) and those duvet feathers are softer and warmer. Duvet is used a lot in pillows, coats and quilts or blankets today. Some animals that have the duvet feathers are gooses or swans. Many birds have duvet feathers too.
They swim about slowly in a circle (sometimes with other aquatic birds) as a group which prevents (up to certain temperatures) the water around them from freezing.
------------
The blood flows throughout the body and helps maintain a steady temperature. So the ducks don't freeze to death or shrivel up and die.
It has a waxy substance on its feathers that doesn't let the water in/through.
Their feathers have an oily substance that keeps the water off.
you would need to get a heat lamp from your hardware store
the ducks feathers keep them very warm same as a goose
Ducks are natural to the cold water and have long feathers to suit their needs. The feathers help the duck swim, fly, and bring warmth in frozen times.
Who says that they don't
Some domesticated ducks only need water to preen in, not to swim in , but yes; wild ducks do need water to swim in.
ducks have to swim under water to get food because they will have no food if they dont go under water and they need water also.
Muscovy ducks can and will swim in a lake. If the Muscovy ducks are domesticated you should not allow them on the lake with other ducks because they can get sicknesses from wild ducks and it is illegal.
Ducks swim in lakes and rivers- mostly small bodies of water. They almost never swim in oceans.most fresh water; Ponds, lakes, rivers
Some kinds can actually swim underwater, such as ducks and geese. Other kinds of birds bathe in water and can put their heads briefly under water.

I believe they could swim in any type of water, please specify.
They have webbed feet
why do ducks swim together in lines
It creates water resistance between the water and the feet to swim.
So they can swim, and eat.
The penguin can swim the longest underwater. The penguin can swim the longest underwater.

swan birds swim with there eyes open or close?swan birds swim with there eyes open or closePenguins can swim on water.Ducks can also swim on water.Swan can swim on water.
Well, this answer is true for penguins and I'd imagine the answer is practically similar for ducks. The blood vessels leading to the feet are arranged to be countercurrent- the heat from the descending arteries is transferred to the ascending veins (which are cooler), so the feet remain at a cooler temperature than the rest of the body, stopping them from sticking to the ice.
