I guess you would candle it just like any other egg. You put the egg on a focused beam of light in a dark room and if the light won't go through and the egg doesn't light up, it's fertile.
28 days
ye
it depends on the type of duck egg you have. i had a cayuga duck, it was incubated at 99 - 99.5 degrees for approximately 28 days.
A fertile, viable duck egg typically hatches 28 days after incubation is begun.
they are used for egg and meat production as well as an ornamental bird
You can't tell if it's fertile or not based on its weight. The same amount of stuff goes into the egg regardless if it's been fertilized or not.
No. If the female attempted to hatch eggs without a male, the eggs won't be fertile, and the egg will just go rotten.
As with chicken eggs, fertilization occurs prior to laying the egg. It takes a week after mating for a duck's eggs to be fertile.
Most duck eggs are larger than a chicken egg. PoultryTalk's Response: Smell the egg, duck eggs have a scent chicken eggs dont. Also most are glossy and sometimes they are a greenish color. Also duck eggs are usually thicker.

The Egg - another species that the duck has evolved from lays the duck egg, and the duck is born :)
You could take to a lab or a vet they have these special machines that can tell if its fertile or not
