Duck Eggs!

Jon down the street has 4 duck nest boxes; with eggs in one of them!

His comment:

With all the avian activity in our backyards this week, curiosity finally got the better of me. So I brought out the ladder after work tonight, and took a look inside four of the nest boxes in my trees. Two were still empty. One had a single egg.  But look what I found in the fourth-----..and it is a good thing I checked. Note the torn and missing screen marking the exit from the box. I'll have to fix that tomorrow afternoon when there is more time and daylight.
