Well, maybe I"ll add a little more detail since it was one of my herds of cattle involved. First I'll describe the weather, that I believe has a major role in the whole thing. It had snowed maybe a 1/4 before turning to rain/freezing rain that lasted till around 1 am, then the temperature dropped to 15 degrees. There was a 1/4 inch glaze of ice on everything the next morning. I have 3 herds of cattle in different areas on the farm. When I went to feed, the first two herds was just like they always are standing around waiting to be fed. When I approached the pasture with the last herd, which is located about 700 yards from the herd I just fed, those cattle was gone and had not finished their feed from the previous evening, very odd indeed. When I finally found them back in the woods, they was acting very unusual, acted afraid of me and did not want to go back where they belonged. They had ran through barbed wire fence in two different places and had covered alot of ground during the night. No cattle or calves had been killed, but they was tore up from running through fence,brush and rough terrain. I first suspected dogs or coyotes, and due to the glaze of ice I was unable to track anything. I thought it just happened to me at first, but later that night another farmer called and asked if I had the phone number to a local trapper that I know well, he said he thought coyotes had run his cattle through a woven wire fence, and wanted something done ASAP, he is located about 1.5 mi from me. He also said the same thing happened on a farm south of him. I immediatly knew something wasn't adding up. The next day I made many calls to cattle farmers in the surrounding area, and soon learned it was a route shaping up and only cattle in a direct path was affected, all had been run through fence of all kinds, was acting strange and would not eat once they had been rounded up. I was able to determine it was a route that covered almost 30 miles in the same night, I suspect it is more than that, but the trail ended at the foot of mountain range. No livestock was killed, but some had to be euthanized due to injuries from going through fence, some farms also had sheep that wasn't harmed, one was a dairy farm were the cows had broke out of the barn and would not go back the next morning to be milked. Nobody including some over 80 years old lifelong cattlemen had never seen cattle in that shape. Nobody seen anything, but many heard dogs raising hell during the night. SteveBNy, you wanted more detail and I could go on, but I think I've might have rambled enough.
