Egg eating might be caused by a calcium insufficiency in the bird's diet. Even if the diet is improved it can continue out of habit. (I am speaking from experience with other birds, not specifically finches)

If you are trying to encourage breeding, give her a nest box. If this is a lone female (they may still lay even if no male is present) she may eat her infertile eggs for nutrition. It taxes their little bodies to produce an egg. Even fertile eggs may be pushed out of the nest and consumed if the bird feels breeding conditions are not optimal.

Another cause may be boredom. Is her cage near a window so she can see outdoors? Does she have enough room to fly around in there? Are there other finches for her to socialize with? She isn't going to get sick from eating her eggs at least.


Hope this helps!

I give them enough calcium supliments regularly, and proper food, there is nest too, but it has laid the egg outside it, now it is trying to Peck and kill it, I don't understand why.

Hi, it may be the nest isn't comfortable for her! If she doesn't have a male to build it then you can try to build it for her, I give mine plenty of hay and also white feathers (fluffy down ones you find in pillows) I also offer them shredded kitchen towel. They love the tissue paper and the hay but not as enthusiastic with the white feathers but all birds are different which is why I offer it to them. I give them different calcium supplement as well as fresh fruit and veg, dandelion leaves are rich in vitamins and easily found.


Make sure there is nothing stressing her out! It could be other birds chasing her from the nest until the egg dies. It could be a cat or fox scaring her.
If she has successfully laid in the past then look for factors that have changed since then. If she hasn't ever been successful it could be she will always eat them as it may be something learnt as a juvenile.
Keep an eye out for her to see if there is anything upsetting her.
You could also give egg food to see if that makes her happy.
