Your chicken might have laid that egg so then she can have chicks. Inside that egg is yolk which later turns into a chick.
The yolk is the food store for a growing embryo, so as it gets older, yolk size will decrease - the yolk is being 'eaten' by the embryo.
because it wants to
a chicken? its like the question: what came 1st, an egg or a chicken.
egg white
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.
Um...A chicken?
a Montague egg is an egg that is laid by a chicken that was owned by a motague
It all depends on the question. If you mean, which comes first, then, according to all scientific knowledge on evolution, the egg came first. There had to be a progenitor species that laid an egg. And that egg incurred a small mutation that resulted in a new species equivalent to the chicken. Then, the new chicken species hatched from the egg.
there is none.
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.
