Every second of every day, somewhere in the world the same scene unfolds.
A batch of several hundred eggs, precisely arranged in uniform rows, moves along a conveyor belt, coming to a halt beneath a machine linked to a jumble of tubes.
Once in position, the machine robotically lowers itself and then simultaneously punctures each egg with a rack of hypodermic needles.
Through these needles, a mix of vaccines and antibiotics is injected into the egg — and so into the unborn chick inside, which three days later will hatch out.
If the scene sounds like something from a science-fiction film, then that is hardly a surprise. Today, large-scale poultry production has precious little to do with green fields and ruddy-cheeked farmers.
