I've watched mine do that every time they see a hawk. Most of the time they see it long before I do. The only way I know it's somewhere around is by how they are acting. One will make that growling/trill sound - everyone will freeze right where they are. I call it the "statue game" like we played as kids. As soon as the hawk moves to another tree - or flys away from them - they all run and hide - I call it the "hide and seek" game. So far they play both games extremely well. Even the 3 week old babies instinctively do this when they are in the run by themselves.
We have several acres of woods, a river and every predator known to man and mine free range, have an open-top run, and I leave the coop open at all times, including night so they can come and go as they please. So far - 6 months and not a single loss to predators. I've learned a lot by watching how the chickens behave naturally - they are smarter than we think when it comes to surviving predators.
