Um...A chicken?
a Montague egg is an egg that is laid by a chicken that was owned by a motague
Placing this question in the context of evolutionary biology, the first chicken egg would have been laid by some precursor species which resembled a chicken but which wasn't actually a chicken.
The egg as such probably isn't much different. But the chicken that laid the free range egg has probably led a happier, more natural Life than a battery chicken.

The egg. Dinosaurs laid eggs long, long before chickens existed.
Eggs are laid and the eggs are collected. No one "picks" an egg off/from a chicken
The female is fertilised by the male before the egg is laid.
The egg came first. According to evolutionary science, eggs have been around for millions of years before the first chicken evolved. The egg was laid by a bird that was not quite a chicken, and the offspring hatched from that egg eventually evolved into what we now call a chicken.
A whiye egg is normally laid by a chicken.
