In this way, chickens pay attention to the line in front of them, Within seconds it becomes motionless. Pretty interesting, right? In fact, there is not one but several ways to put chickens into a trance, and the result is always the same for the poor animals.

Well, a chicken How is it so easy to get hypnotized?

As can be seen in the video, the fact that the chickens fall into a trance within seconds is actually the result of tonic immobility and not hypnosis.

Tonic immobility, which is very different from hypnosis a reaction that reinforces fear and the chicken faces involuntary paralysis, convinced it will die. Tonic immobility causes physical disability but is reversible.

Farmers and scientists have been aware of this reaction in chickens since 1646. Moreover, this response usually in domestic birds such as chickens and quails is seen. A study also conducted in 1928 found that lizards and rabbits also undergo tonic inactivity.

Both we and animals can experience tonic immobility as a result of various traumatic events. At this point, researchers checked the brains of a group of people who had been traumatized and found that most of them had an increased heart rate and a so-called tonic inactivity. an involuntary defensive strategy revealed that he was developing

Let’s get back to the chickens.

Chickens exposed to tonic immobility for 15 seconds; As their heart rate, breathing and body temperature accelerate; This 15 second process can increase to 20-25 seconds in cages rather than coops, in large flocks rather than small flocks, and in birds separated from their flocks.

Many methods can be used to induce the chicken into this trance state. For example according to the oscillating finger method Place the chicken on a flat surface and make sure the top is pointing towards the ground. A wing is placed under his body and he is allowed to lie on his side.

Then one of the fingers of the hand is placed in front of the chicken’s beak. is moved back and forth and the finger is moved forward from the tip of the beak without touching the beak.

The chalk line method, discovered by an old farmer named Almanac, begins by laying the chicken on its back with the beak pointing down.

Using your finger or a stick, draw a straight line about 12 inches (30 cm) on the ground. So chicken, Notice this line and tonic immobility will occur.

Another way to put a chicken into a trance is the mimic method. This method is possible by imitating the movements of the chicken. Namely, after the chicken is placed on a flat surface, its head is tucked under its wing and His whole body sways sideways.

Constantly shaking chicken jerks and When the movement is suddenly stopped and falls to the ground, the tonic passes into silence.. This inactivity usually lasts between 30 seconds and 1 minute, but if you look into the chicken’s eyes during all this, the chicken can remain in tonic inactivity for about 3-5 minutes.

We still recommend that you do not consciously subject chickens and other animals to tonic inactivity, as they will You may face many physical and mental problems Let’s not forget to remind you.
