Is chicken hypnotism true or false?

SnapFactAttack on Instagram: "A trick where a person holds a chicken’s head close to the ground and draws a straight line in the dirt moving away from its beak. This triggers a natural reflex called Tonic Immobility, a temporary state of paralysis that makes the chicken stay perfectly still. The video shows the chicken remaining in this "trance" even after the person lets go, until it is eventually snapped out of it. #ChickenHypnotism #FarmLife #AnimalFacts #BackyardChickens #PoultryMagic"
