Egg first or chicken first?

Competition entry:
Egg first or chickent first? a millennia old catch 22 argument which has been disputed over and over throughout the years. To settle the argument, I lay down the following facts.

The egg came first
Some will say
But the chicken came first
By the river Tay

The egg will not hatch
By the freezing river
Unless there's a chicken
to highten the temperature

The egg needs a guardian
for protection and warmth
and that the chicken provides
beneath its motherly form

Without the chicken
the egg will not survive
the egg will not hatch
if it is deprived

and that's proof that the chicken came before the egg.
