I didn't get that at all from the beginning. I do agree that it was some time ago, but it looked to me like they were following the chopper. Then they were all going somewhere through the woods when they heard the gunfire from Shane and turned towards the farm.

What we've seen in the past is mostly they mill around, like in the city. The only other time we've really seen a herd of them was on the highway when Sophia ran away
