For Wooly worms to predict winter (I`m told) is to see thousands of them. I`ve seen only yellow by the house, Half brown ans half black in the yard, and all black in the garden.
I do remember seeing thousands of a black on the road one year and it was a very bad winter. Early winter hair on the animals is a sign of cold winter, mine don`t have any yet. One of my rabbits has a line of long hair just along his back like a mohawk hair cut.All I know for sure is it was 80 degrees here in mid Wisconsin today and that`s a miracle! God willing we will all make it through another winter.
