you really cant.. DONT TOUCH THEM. just leave them alone. the mother hen knows if there fertile or not. if there not fertile she'll push them to the side, if they are fertile she will sit on them. but sometimes a pushed aside egg is fertile
and also it is always warm as the person said above DON'T TOUCH THEM!!
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.
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.
pick up the egg
You could take to a lab or a vet they have these special machines that can tell if its fertile or not
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.
Well, it sort of depends. If the female is laying/sitting on the egg that might mean it is fertile, but only if she is either trained or knows how to do that. But sometimes, the egg will be fertile, but the female won't know what to do, so she won't sit on it. Also, do you let your bird mate, because if you do the egg will most likely be fertile.
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
No
the goose laid a golden egg.
The one way you can tell if a chicken eggs is fertile is by holding a strong flash light behind it and if you see the embero it is fertile
