How do ducks do through the winter?

[Wifezilla]

Mine usually lay right before I let them out of the night pen. I didn't lose a single egg last winter. Pure luck, I know, but I am NOT complaining.

Never lost any either. They almost always would lay in their house, and the duck's body heat kept that warm enough. When I let them out in the morning the eggs were there.
