I am one who has had a hawk kill a bird right in front of me. It happened so fast I didn't have time to react. It didn't take her but did kill her. I had another incident where I had some chicks out in a little temporary pen and a hawk swooped in and grabbed a chick and took off with it while I was standing right next to them. Again it happened so fast there wasn't any time to react except to watch the hawk fly off with the chick. I don't free range anymore due to losses from predators and it's a risk I'm not willing to take anymore. If you're distracted for a moment a predator may sneak in and take the the advantage of an opportunity. Now my birds all have nice large secure pens. Luckily I have the space. Good luck...
