Animals killed by lightening isn't that rare, talk with ranchers. My great-grandfather was pushing 10 or 12 head when lightening started striking, he left the cows and headed for the house. When he went back after the storm all of them were dead. Both of my grandfathers had stock killed by lightening, in fact both of them got hit by it while out irrigating. One of the twice. Was up around Seligman in 2004 and there were a couple carcasses laying in Chino Valley, when I told the ranch mgr about them he commented he knew, lightening got them.
