Chicken Hypnosis

Can this be true?

Futility Closet

"You can hypnotize a chicken by holding its head against the ground and drawing a line straight outward from its beak. Most chickens will stand immobile and stare at the line for about 30 minutes. One remained hypnotized for 3 hours 47 minutes."

I am afraid to hypnotize a chicken. I am afraid she will drift off to some faraway chicken place and never come back. Chickens have very limited resources: a beak, two sets of claws, and sharp eyes. A chicken in a stupor os a helpless creature indeed. Girls, I need you to keep your wits about you!
