motion sensor lights

[cmom]

I have put up motion sensor lights but the predators got used to them, but then you know if something is there if you're awake. Some do have alarms that will go off when the light comes on. I have electric wires around my coops and pens and nothing has gotten past them. Good luck...

I tried that but with my game cameras I found that it was going off even as all kinds of things walked by. Cats, possums, etc., so they all got used to it pretty quick. That said, I've heard some people have good luck with them. In my opinion, it shouldn't be the only trick up your sleeve. That, some blinking red "predator" lights, etc., all should be part of the defense.
