Summarize the following:
Ducks tolerate cold very well, but tend to dislike wind. Make sure your ducks have some protection from the wind over the winter. This is important to their health and overall well-being. Hang a tarp up in one corner of your duck's pen. If it gets windy, your ducks can shield themselves behind the tarp. You can also purchase a small outdoor wind shelter for your ducks. When they breathe, ducks tend to emit a lot of moisture. This can cause health conditions, such as frostbite, in the winter. A duck shelter should never be completely closed off from outside air. Keep some air vents in the shelter. You can use mesh material on some parts of the shelter, or install small windows. In order to protect your ducks from the cold and from predators, vents should always be up high. Do not install any air vents on ground level. Ducks enjoy swimming, even in the winter. While most ducks can tolerate water at cold temperatures, it's best to err on the side of caution. Wait until a sunnier, warmer day arrives to set out a pool for your ducks. Use a deep, wide pool on warmer days to allow your ducks to swim and bathe.
Make sure to protect ducks from the wind. Ventilate your ducks' shelter properly. Allow your ducks to bathe on sunny days.
