I am about to take my third trip to Colorado City, Texas at the end of next month. This is near San Angelo. I regularly kill foxes here in East Texas, but I have only killed one fox on the ranch in Colorado City. Any tips would be appreciated. Are there not as many foxes out West as people say. The property is 2500 hundred acres and is not pressured at all. I am the only one calling it. I know to use bird sound and screaming gray or platinum gray but they just don't show up.
