Those old hawks are so swift and silent. Is it possible for you to do anything about the hawk, or is it protected? Even with cover, if the predator is that silent when attacking, you will continue to have losses. I am not criticizing you for your losses, I know your chickens must be happy, being able to forage for weeds and bugs, and I'm sure they lay beautiful eggs, too. I'm just concerned that you have already lost a number of birds, and your favorite among them. I'm sorry for your loss.
