Has anyone tried the "garden eyes" raptor deterrent? It's a huge yellow inflatable ball with big reflective "eyes" on it. We live in the woods in NC, and my chickens are about 16 weeks old. I really want to let them out for at least a little while every day, but I'm terrified of the hawks getting them. I know we have them, I've seen them almost every day since I moved here, well before we had any chickens. If anyone has tried anything that really worked, please let me know!
