identical twins, if the egg divides in 2; identical triplets, if it divides into 3, and so on...

Catholics do not have a separate definition for life, they believe the same thing as science, a new life begins as soon as an egg is fertilized with a sperm.
The fertilized egg cell is called a zygote and divides to form an embryo.

When an egg was fertilized by a sperm cell.
A zygote is created by the fertilization of two haploid cells created by meiosis. Because a zygote is fertilized by two haploid cells, it is diploid. It then has to divide and grow though mitosis like any other body cells.
Technically, an unfertilized egg is not alive. Since this question is in regard to chickens...the egg itself will develop normally and will be laid by the hen. The unfertilized egg will begin to rot during incubation whereas a fertilized egg will start to develop into a chick.
A fertilized egg, a zygote, stays as a single cell for about a half an hour before its first division.
In humans, eggs are typically fertilized in the Fallopian tube. The fertilized egg begins to divide and continues down the tube and implants in the uterine lining. If it implants in the Fallopian tube, this is known as an ectopic pregnancy (bad). In a chicken also, the egg is fertilized in the first part of the hens oviduct.

The new cells are smaller than the egg cell.
The most immediate external effect of an egg being fertilized, is that a change occurs in the egg such that it either repels all other sperm, or at least is no longer accessible to them.
