Eggs Over Winter?

   The ducks are just approaching 20 weeks old.  They are on the cusp of egg-laying maturity.  We are eagerly awaiting our very first duck eggs.  New marsh hay has been laid out in the garden beds where they rest.  Fresh, clean shavings fill their coop.  And their solar light keeps them up and going longer than they normally would as the sun melts beyond the horizon by 6pm (soon to be 5pm thanks to Daylight Savings).  We're hoping the Cayugas will produce some black eggs before Spring.  Cayugas produce black eggs that eventually turn white as they mature.  Blue Swedish ducks lay white, blue, or grey eggs.  And the Buff Orpington duck will lay white, tinted eggs.  Snagging eggs before they freeze in our Wisconsin winter will become quite the game for the kids and I.
