Finding eggs?

[Razorpig]

I have a pair of mallards and 3 campbells(2 hens and a drake). I am having trouble finding their eggs. The pond is not very big and i do not see there being very many places where they can hide them but i havent had any luck. Anyone have any tips? Is it possible they are not laying yet?

How old are your ducks? And what season is it currently where you live. These two questions will tell alot as to when you should be expecting eggs.
