Bummer... Swooping predators are my nightmare, they are the one critter that can really hurt a flock and you can't control them easily.
Like a said taking an Eagle, hawk or falcon out of season* is a nasty crime up here..
I really do not know what I would do if they became a problem.
* for those of you with no sense of humor, there is no season on raptors anywhere.....
Yeah but chickens around here seem to be toxic, several hawks were found dead from lead poisoning after consuming some of the neighborhood birds.
