I am saying that mass animal deaths can occur, independently of electrocution, and this diagnosis was based on circumstantial evidence. One might tend to blame lightning, as a sporadic, isolated event, so as to prevent fear of contagion.
Regardless, I thought it was unusual and newsworthy. No offense is intended, toward the OP, who brought us this interesting story.

The photo clearly shows the animals piled up together. And they have healthy (though dead) carcasses.
A disease would have taken some amount of time to kill the animals, and they would have wandered around being sick for hours or days or weeks before they keeled over. And would there would be evidence of the disease ravaging thier bodies. These animals all got zapped instantly, and died suddenly en masse. And all have beautiful carcasses.
