Mostly they are very quiet except before they lay their eggs and they squawk then after when they blast out their egg song - which I have learnt is also a predator call/alert. I have read that they do this egg song to 'lure any predators' away from their eggs. I can believe that, and have seen many other birds do the same thing.Ain't that the truth!
My silkie hens make the most noise out of all my chickens! They almost sound like small geese to me. If they see a cat, they warn the whole neighborhood!![]()
