Chicken Hypnotism

One can hypnotize a chicken by holding its head against the ground and drawing a line straight outward from its beak.

“I recollect particularly a case of catalepsy produced in a cock,” writes Gaston Tissandier in Popular Scientific Recreations (1882). “We place a cock on a table of dark colour, rest its beak on the surface, where it is firmly held, and with a piece of chalk slowly draw a white line in continuation from the beak, as shown in our engraving. If the crest is thick, it is necessary to draw it back, so that the animal may follow with his eyes the tracing of the line. When the line has reached a length of about two feet the cock has become cataleptic. He is absolutely motionless, his eyes are fixed, and he will remain from thirty to sixty seconds in the same posture in which he had at first only been held by force.”

Most chickens will stand immobile and stare at the line for about 30 minutes. The record, reported by Hamilton Bertie Gibson in Hypnosis: Its Nature and Therapeutic Uses (1980), is 3 hours 47 minutes.
