Thank you for your" feel good story" , Tweety is quite the girl!! I like her attitude throwing the bigger hens out of nest boxes, etc. Tweety likes to kick behind. As far as other hawk deterents, I've saw one feed store had "windsocks," of different birds and they move and change direction continually with the wind. I think they might be good for scaring off raptors, as they have unpredictable behaviors.
