I recently read about putting red lights outside the coop to ward off predators. I mentioned it to hubby and he said they see the light and think it's the eye of their predators, which scares them off. I saw some lights that are sold for this but hubby said all you need is a red led light. So I said good, put some on my chicken house please. While he's at it I might have him put one on our deck facing my bird feeders the coons and opossums like to get into at night.
