How will you identify fertilized egg from unfertilized egg?

Answer 1

The only way without any incubation is by cracking the egg and in the yolk there will be a small white dot, sometimes barely noticeable, and sometimes it can be grey or even black.

The other way to tell is by incubating the egg for at least 6 days and then candling the egg which is done by done by using a bright light against the egg so you can see and it has veins all over. if there is no veins by 10 days it would be fertile at all.

Answer 2

There is really no sure way of being sure, though there are ways.

If there is a male duck present and the ratio of females to males is not too high, about one male to every three to five females is about right, then chances are the eggs are fertile.

A sure way to tell is by candling the eggs, or looking inside the eggs. This should be done at around the tenth day of incubation. Make a candler by poking a hole in a tin can with a nail and shining a flashlight through it. Rest the egg above the hole. If the egg appears red, or an embryo can be viewed the egg is fertile.

Mainly you may have to just wait and see if the eggs hatch.

Answer 3

You "candle" them. Use light under egg to check for the shape of a baby shape.

Answer 4
