For anyone out there thinking about buying the "predator eyes" Don't waste your money. I have had them surrounding my coop for a year now and they do not work with coons, cats or dogs. I can't say with foxes because I've only had foxes in my yard twice in the last two years. I know this because I also have cameras all over the property. The best deterrent I've found is a good motion control system and a shotgun. I haven't seen a coon on my cameras or in my yard for close to 7~8 months. The first time they come, they get rock salt. If they return they get birdshot in the tail. If they come back, they don't leave. P.S. rock salt don't work with skunks, they will come back till you makem stay. I've had no losses ever other than natural causes.
