After 3 years I've had my first fatality due to a hawk attack. My poor girl was ripped open in front of her flock a mere 10 minutes before I got home. I've been keeping everyone in their covered run since then, but I feel terrible since they love to free-range and forage in the backyard. I've been trying to provide stimulating activities to keep them entertained, but it isn't the same as being able to run free. I've read about scarecrows, strings of lights across the yard, netting, etc. In your experience, have any of these proven effective? The damn hawk was back the next day so I don't dare risk letting them out unless I'm right there with them.
