I’ve had mixed results and don’t mess with it anymore.
But, what helped a bunch was we made our own tail out of a brown and white sock sewed together with a coat hanger for shape. Before we closed it up we placed a doe bleat inside of it, then fishing line from the tip of the tail, over a branch and back to the deer stand. Pull on string, tail raises up, bleat can loads up, lower the string and a bleat comes out of her backside…it was comical at times to see the reactions of the deer.
