I was losing a hen every other week.
Hawks used to hit my yard constantly: attacks every couple of weeks, close calls almost daily. Decoys and tricks didn't last.
So I built a small device that watches the sky and kicks on a Skydancer for thirty seconds whenever something enters the airspace.
From the moment I installed it, no attacks. Hawks still pass by, but the large, random movement signals danger, and they move on.
This changed everything.
