>Sheep have a strong tendency to keep together. This may often help to protect them, but in combination with a low intelligence, it may sometimes lead to this kind of unfortunate incidents. But I am still surprised that over a 1000 sheep followed the first ones.

I've seen such behavior once. Two of us in a Yugo on top of a bridge, and a herd of sheep coming from the other direction. And they all stopped at the dilatation combs - for some reason they were afraid to walk over iron. They spread all over the bridge up to that line, and wouldn't move until the shepherd waded through the herd, took the leader ram by the horns and pulled him over the iron.

Then all the sheep went over... but the first row of them, who saw where the ram was pulled over, insisted on crossing at the exactly same place. The others behind them didn't exactly match the place and once the first 20-30 of them crossed, they were all over the bridge. Now imagine sitting in a Yugo on top of an arc of a bridge, sheep all around you, river below... :).
