I realize this is an older thread. Most as any hawk will kill a bird if it gets a chance. I have had my share also. Now my birds have nice large covered pens. I still see hawks now and then but they can;t get to the birds. A couple of times I have lost a bird to a hawk standing right nest to them. It happened so fast I didn't have time to react. One took one of my chicks and all I could do was watch it fly off with my chick. Good luck...
