As with any bird's egg you can use a technique called "candling". All you need to do is hold the egg over a bright light such as a flashlight. If the egg is more than three days old and is is fertilised you will see a dark spot inside and a criscrossed lattice of blood vessels just inside the shell. When the fertilised egg is about eight days old you may even be able to see the embryonic chick wriggling and kicking inside and if you are very lucky the heart may be seen beating. This technique does not harm the egg in any way.

After the female lays the eggs both parents will incubate them 24/7. Thats the easiest way to tell if they are fertile. You could candle the eggs by using a small flashlight and holding it up to the egg, if it has a network of blood vessels running through it than it is fertile. I do recommend doing this though as the parents may abandon the eggs if your scent is on them. Lastly, if the eggs are infertile they will most likely be tossed out of the nest or they will be laid outside of the nest. Hope this helped.

Do you have to hand feed baby zebra finch?
No, finches, especially Society finches and Zebra finches, make very good parents. For Zebra Finches, if one of the parents die, the other will feed and take care of it. If you want to hand tame a ZEBRA FINCH to be a good companian, you should hand feed it at an early age.Wait until they are 4 weeks old!!!!! You don't have to feed them in order for them to survive-the parents will take good care of them. One way to tell if they are being fed often is to look at their 'crop'. this is where their neck is. If it is bulgy and fat and full of seeds, you know that it is being fed properly.

How you can obtain fertilized and unfertilized egg from hens?
Once hens are of a certain age, they will produce eggs. If you want an unfertilized egg, don't put the hen with a rooster. Depending on the breed, she will give you 1-6 eggs per week. If you don't have a nest box for her, she will make a nest on the ground. If you want fertilized eggs, place a rooster with the hen, make sure the rooster knows his job, and the next day you may have a fertilized egg. There is a way to tell if the egg has been fertilized once it's cracked open, but through the shell, you can't tell until the egg is incubated and the chick starts to develop.
Do grocery stores have fertilized eggs?
it doesnt matter if they are fertilized as it doesnt affect the taste, etc. Factory farms dont keep roosters with the hens much less give them enough room to mate even if roosters were present so if you buy eggs from the store, they wont be fertile. When you crack a fertilized egg you can see a small white spot orf bullseye on the yolk. it doesnt matter if they are fertilized as it doesnt affect the taste, etc. Factory farms dont keep roosters with the hens much less give them enough room to mate even if roosters were present so if you buy eggs from the store, they wont be fertile.
