This nest box design is also the favourite of the resident Wood Ducks on my property. The design is by Hollow Log Homes, with a slight modification of a shorter height, and lower entrance to reduce the risk of ducklings not being able to jump out.

And also info on what materials to use, and not to use, when making your nest box.
