Is it true that you can hypnotise a chicken?

If YouTube is anything to go by, chicken hypnosis is quite a popular pastime. It involves holding a bird on its belly and slowly drawing a line with a pen or finger from the tip of its beak into the distance.


The result is a floppy, prostrate animal apparently oblivious to the world around it. Hypnotism is probably the wrong word, though. The trick is thought to be a gentle way of inducing ‘tonic immobility’, a state of temporary paralysis that enables an animal to feign death when cornered by a predator.


Similar methods work on other species, too. Rabbits and sharks, for example, can be immobilised by turning them on their backs and stroking their muzzles – a technique that is employed by vets and marine biologists.
