So now I have access to local chickens and fresh eggs. One does what one must.
However... that being said... if you can raid a duck's nest and get freshly laid eggs (a black marker is good for marking older eggs)... duck and goose eggs are to die for when making scrambled eggs, omelets, or over easy. Big, rich, and full of flavor. I never pass a chance to steal duck eggs.
But mark them. First day you check the nest when mom is off it. Mark all of them.
You can take the unmarked ones the next day.
Getting an older egg is less than optimal.

Don't use a “permanent” marker as it may make the future ducklings ill, esp. if you mark the end that has the air sac.
