I have seen threads of things to deter hawks but do CDs work? Anyone have experience? and if it works how many and where do I put the CDs. I have a covered run but the chickens love to free range and we only let them out when someone is around, except even a human is not a deterrent. Yesterday, a hawk zoned in on a chicken but as it was coming down a mourning dove got in it's way and scared the hawk off. It was actually pretty fun as the hawk tried to stop and literally looked like it was flying away with it's tail between it's legs.
