$24.95 Nite Guard: Thousands of these lights have been sold to poultry producers who have successfully stopped nighttime predators such as owls, raccoons, opossums, coyotes, and foxes. The manufacturer guarantees that the light will also work for you, or you will get a full refund. The Nite Guard is a maintenance-free, flashing red light unit that receives its power from the sunlight. The unit is completely sealed and weatherproof, with dimensions as follows: 2 ½” wide, 2” high, and 1” deep. We have found that placing a light in all 4 directions will provide better results. If you place only one or two lights on your post, you will find that the predators will approach from the direction where the lights are not placed. The price includes handling and shipping; however, if possible, order along with your baby poultry order.
