We have a large yard where I can see the sky real well. I also am home most all the time. I use bottle rockets. Now my silkies have a covered run but my LF free range all day. If they see a hawk they go in the barn in a stall. Just want them to know this is a No Fly Zone. They do have a covered run, there food, water, and nest boxes are in there. I keep the car or the truck clost to the barn for more cover. They are under and around the car a lot. If you work or in the house a lot bottle rocketts might not help. This works very well for me. Good luck
