If a mama duck gets scared and leaves her nest it is fifty degrees outside how long will take for the eggs to die?

Duck eggs can survive for up to 24 hours if they are left alone. However, if the temperature drops below 50 degrees Fahrenheit, the eggs will start to die. So if a mama duck leaves her nest for more than 24 hours and the temperature drops below 50 degrees Fahrenheit, the eggs will likely die.
