A male duck copulates with a female duck and she will lay a fertilized egg. If copulation does not occur she will lay an unfertilized egg.
A mother duck lays a fertilized egg to get a baby duck.
egg yolk isyellow and fertilized is called balut
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, the egg has to be fertilized by the male duck for a chick to grow in the egg This is why when you crack open a chicken egg to fry, there is no chick inside.
You have to candle the duck egg. Hold the egg up to a light or a flashlight, and measure the air space.
You get a dead chicken, or duck. But you can get a chicken/duck tree, depending on the season, lighting, and waterness.
you can't tell when an egg has died if a duck hasn't been nesting on it but if the duck has been nesting on it take the egg and place it in a jug of Luke warm water and if it sinks it has died and if it float luckily your egg is alive
You can do the same things with a fertilized egg as you do with a store bought egg. The one advantage of having fertilized eggs is that you can incubate the fertile one's and produce chicks. Fertilized eggs taste the same as a "store"egg and you cannot tell from the appearance that there is any difference.
A male duck can try to mate with a female hen. However, this does not usually lead to a viable, fertilized egg.
The only way to tell is to keep it at 100 degrees for 21 days. If you get a baby, it's fertilized. If you don't get a chick, crack it open. Was a baby forming that died during the 21 days or is it a stale egg? If it's just a stale egg, it wasn't fertilized.
