What is Reddit's opinion of Solar Powered Predator Deterrent Light Scares Nocturnal Nuisance Animals Away, Deer Coyote Raccoon Repellent Devices, Chicken Coop Accessories?

If you haven’t seen the bodies/feather piles for the last two, try not to give up hope. I’ve had chickens disappear for a day or so after a predation event, and show back up. Piles of feathers don’t always indicate death, as scared chickens can “blow their butts out” when they’re fleeing a predator. Try to leave the coop open for them so that they go back inside if they’re still out there. I’m so sorry that you’re going through this.

I would suggest something like this, I use it for my coop to keep away predators, and we live in an area with bears as well. Since we’ve started using it, we haven’t had any issues. I hope you’re able to find something that works.
