Do ducks have to mate for each egg?
You don't need a male duck (called a drake) for the females to lay eggs, but they won't ever hatch into ducklings without a drake around. Also, ducks tend to be better year-round layers than chickens, continuing their egg production right through the winter without any added light.
Do ducks lay unfertilized eggs?
For those of you less familiar with the workings of farm animals, ducks and chickens will lay eggs regularly but they are unfertilized eggs (sort of like women having a menstrual cycle with their unfertilized eggs).

A mother duck sits on her eggs for 20 to 23 hours a day, taking an average of three breaks, each lasting around an hour at a time. When she does leave her nest, the duck hen covers her eggs with additional down and nesting material to help keep the eggs warm in her absence.
Can a duck lay 2 eggs a day?

Why did my duck lay an egg with no shell?
There are three main reasons ducks lay soft-shelled or rubber eggs and these are lack of calcium in their diet, lack of vitamin D in their system, or because they are young birds and their oviducts and not fully developed yet. Ducks may also lay soft-shelled eggs if they are stressed or unwell.
