How long can a duck egg be cold before it dies?
Eggs kept cold for longer than 7 days before incubation will result in a loss of hatch due to embryo cell death and a decline in internal egg quality.
How often does a duck lay an unfertilized egg?
Depending on the species, nesting waterfowl can produce one egg every 24 to 48 hours. Each egg is fertilized and formed as it travels through the female reproductive tract. Ducks lay one egg per day, geese lay one egg every day and a half, and swans lay one egg every two days.

How can you tell if a duck egg is still alive?
