Hypnotizing Chickens?

On the Strange Animals Blog is a post about “chicken hypnosis” (Beredimas, 2014), which is more accurately referred to as tonic immobility–“a state of reduced responsiveness induced by physical restraint” (Bryan Jones & Faure, 1981). Tonic immobility is thought to be an adaptive response to situations that cause chickens to become fearful, similar to animals “freezing” when they become aware of a potential predator.

Tonic immobility can be induced in several ways, but the various techniques typically involve physically restraining the chicken for a short period of time. Here is a video showing one of the techniques (other videos of “chicken hypnosis” induction techniques can be found here).
