The internet is baffled by videos coming out of a farm in China. The videos show a flock of sheep walking in circles non-stop for 12 days straight.
Nobody seems to have a good reason that sheep would behave this way. Although there are some diseases in animals that would cause disorientation, it's hard to say that it would create an organized circle of over 100 sheep like this.
To this day, scientists still don't have answers for why animals move in circular groups such as this one.
