Tonic immobility
One can also hypnotize a chicken by mimicking how it sleeps  with its head under its wing. In this method, hold the bird firmly, placing its head under its wing, then, gently rock the chicken back and forth and set it very carefully on the ground. It should stay in the same position for about 30 seconds. H.B. Gibson, in his book Hypnosis: its nature and therapeutic uses, says the record period for a chicken remaining in hypnosis is 3 hours 47 minutes.
