An egg that has not been fertilized by the rooster's sperm is called an infertile egg. a hen will lay infertile eggs without the assistance of a rooster. Commercial egg layers have never and will never know what a rooster looks like, but they will produce an infertile egg 6 days out of a 7 day week.
A duck egg of course! They taste very good too!
There is nothing different if you are talking about a live egg as there is a chick growing in side of it. a fertile egg is when the daddy rooster make the egg fertile
All chicken can lay egg but not a fertile egg.
to feed the baby if the egg became fertile
After 3-10 days of the bird sitting on the egg, take the egg to a strong light and if it has redish vines in it, then it is fertile. If it's just white then its not.
you don't need a male to have a fertile egg... the female body needs to be healthy and fertile to make a child which that part does take a male
the egg that is fertile will have a bump on it
It is almost impossible to tell a fertile from an unfertile pheasant egg just by looking at it. If you hold it up in front of a bright light, in a process called candling, a fertile egg will show a dark spot inside and a network of red blood vessels within the egg.

The egg is fertilized in the womb.
Do you have a Rooster living with Hens? If so, chances are, yes, the eggs will be fertile. If the hen is brooding, meaning she is sitting on top of the egg to keep it warm, then it's probably fertile, if not, then it's not fertile. In any case should you have a rooster and a hen together, and the hen lays an egg, and it doesn't brood, then you should keep the egg warm. I think to check just hold the egg up to a light lol.
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.
