“Then it’s the Andromeda Strain, because nothing, *nothing* biological kills off an entire herd at the same moment.”
True, but nothing in the article claimed that they all died at the same moment, the same day, or even the same week. It just said that 200 cows were found dead in a field. It is also possible that a large number of them were in very poor condition, and the recent cold wave provided the additional stress to finish them off.
The article did not mention how many live cattle were found in the field with the dead ones.
Might take the fun out of it. Might give people the idea that it was natural.
