I heard a huge commotion for about 1/2 hour... sounded like egg laying screams but they went on and on... Went out to see what the deal was and the girls were all huddled under a bush that is in their run still screaming... Then all of a sudden I see a hawk fly off the top of the run and perch in a tree a few yards away. Chased him away with a small rock (I missed) and he came back three times.... I have a gut feeling I will need to do something a bit more aggressive to change the hawks desire to hang around. Any tips?
