Sorry if this isn't the right place to ask, but (what we believe was) a female mallard duck made her nest on our property and laid her last egg about two weeks ago. This morning we found her dead on the property (no sign of blood or trauma, no idea what did it) and her nest uncovered. Is there any way to save her eggs, or is it now hopeless? It has been getting down to about 55-50 degrees Fahrenheit here in northern California at night, at about 65-70 degrees in the day. Thanks for any help you can provide!
