Hard to say. They started looking here in December, but I haven't seen any ducklings. It wouldn't hurt to get the boxes up. Put some pine shavings in them. Change the pine shavings each winter.

The ducks looked mine over last year but I think my shores were too bare. This year I'm starting to get shoreline plants and they seem to like it here.

If you do: I'd suggest using cheap 4" PVC for the poles. Coons and snakes find it too smooth to climb. Some even recommend coating the poles with grease. I don't do this. I did camo paint the poles with spray paint. The poles are almost invisible.

If you can put them over water it is safer from predators, but the kids can take a long drop to hard ground with no problem. Whatever works.
