Clarifying when life begins, or doesn't!

When a sperm fertilizes an egg, the result is a cell called a Zygote and has all the DNA of both parents. The Zygote then begins to divide by mitosis to produce a multi-cellular organism which becomes an Embryo.

The debate about the “right to life” involves many groups who believe that life begins at the moment of fertilisation of the egg. This appears to be the official position of the Catholic Church.
However, Church practice today, Ash Wednesday, appears to contradict its own interpretation of when life begins.

Let me explain.

Ash Wednesday (and Good Friday) is a Fast Day for Catholics, when they are forbidden to eat meat. This prohibition includes chicken and other poultry.

However, Catholics are permitted to eat fish and eggs on Fast Days. There is no distinction made between whether the eggs are fertilised and unfertilised. But if the egg was fertilised, and the Church believes that life begins at fertilisation, then such a fertilised egg would, if fact, have become a chicken in the eyes of the Church and its consumption would consequently be prohibited on a Fast Day.

Should I send this to the Pope?
