So my flock of 28 is almost old enough to get to free range a bit. I have been looking into some predator prevention.... reflective tape, fake owls, etc... when I stumbled onto this! I was wondering if anyone else has tried it and if it was awesome or not worth anything? It's a motion sensored water sprinkler system. https://www.amazon.com/Orbit-62100-..._UL160_SR160,160_&refRID=QKJ3E9MDTJ97RC14029T Thoughts? Thank you in advance!
