Hawk repellent

For all you other chicken ranchers out there, I've discovered a great way to keep hawks and eagles away. Just set up a large telescope inside a glass porch, aimed at their favorite perch. I set it up Sunday after seeing the eagle and two hawks. They must think it's a cannon, because I haven't seen a hawk since my first post. But, then again, it might have something to do with the foot of snow still on the ground.
