How to make a nest for my duck?

[smileylife]

My duck recently started laying eggs, but since she doesn't have a nest she just lays them on the floor. She sleeps in my room and has a little 'house' but for some reason she wanted to lay them by a mattress I have. There a small hallway in my room (it leads to a wall) and we just put a bunch of stuff we don't use there. Every morning around 6 or 7 am my duck goes in that little hallway and starts scratching the floor and lays her eggs there. What's a good way to make a nest?

Have you tried moving the eggs she does lay to the spot where you would like her to lay them? Sometimes depending on the breed you can move the eggs and the duck will move with them.
