Are all pareve items kosher

Eggs from any kosher bird (chicken, duck, etc) are kosher. However, you must check for blood spots in the eggs. If you find a blood spot, throw away the part of the egg that has blood, some people won't eat the whole egg. If the blood spot represents a chicken embryo growing in a fertilized egg or if there is a fertilized embryo in the egg, no part of the egg may be eaten.

It is also worth noting that since ostriches are not kosher, ostrich eggs are not kosher either. The same applies to all non-kosher species of birds. Additionally, the rule that eggs of a kosher animal are kosher and eggs of a non-kosher animal are not kosher also applies to fish eggs.
