why do chickens get hypnotized by drawing a straight line?
In: 844
I had this demonstrated to me in an Animal Science class in college. The explanation I was given was that due to the position of eyes on side of a chickens head they can’t see an area directly in front of them (about a ten degrees slice) when an insect or moving object moves into that blind spot the bird brain freezes them until it emerges on the other side of the blind spot. By drawing a line into the Blindspot and then tracing straight away from the chicken out of sight, the chicken just freezes waiting for the movement to continue out the other side of the blind spot. Take this for what it’s worth. I didn’t pursue animal science beyond this intro level course. It wasn’t presented to us a particularly useful knowledge more of a novelty.
