So sorry about your loss.
I know a number of people who have hung old CDs and DVDs around and in their uncovered runs and they haven't had hawk problems since then. I am going to do the same when we get our ducks; they will have a covered, secure run but will somtimes have daytime access to an open run next to their pen (veggie garden). You can also get bird scare tape, or use strips of mylar balloons. Hope this helps.
