You are never within your rights to shoot a hawk! They are federally protected! We deal with hawks by just keeping our chickens confined til they go away; they will hang around and you'll see them; after a while they'll get discouraged if they can't get your chickens, and they will leave; wait another forty eight hours or so after you don't see them hanging around anymore. Cover the top of the coop, and give your birds something to shelter under; they're good at spotting the hawks when they're out. It's one thing to shoot,trap, or relocate a possum or raccoon; but there's a reason why certain species are protected. Sorry, we love our chickens (we've been jumping through hoops for ours lately!) but my personal theory is; do everything you can that's legal to protect your birds, but you might as well resign yourself to the fact that you're probably going to lose a few to predators, and everything else under the sun. Chickens were never meant, or designed really, to last long; they were designed by nature to be food. Roosters are great for protecting your flock from a lot of predators; especially if they're free range. We've never had to destroy or relocate a predator of any kind in almost two years (fingers crossed)! There are other ways to get them to go away, most of the time.
