Have you thought of using firecrackers/black cats/bottle rockets/Roman candles to ward off the hawks. It could work? Inexpensive and perhaps effective in making them feel unwelcome. Best defense is a good offense”Ask me anything - I am currently going through the process of applying for a permit from the US FWS for depredation. I have a swarm of red tail hawks that have moved from the farm down the street to the woods in my backyard. Its only a matter of time. I have a steel wire covered run and it is secured from all sides, with one side being a 6 foot tall wooden fence. The hawks perch on the fence and torment my poor ladies. I have it on video. I run out there screaming at them and flailing my arms but they just fly away and perch on a branch in my backyard that's JUST close enough to infuriate me and to make my hens scared. I throw rocks at the trees to make noise (obviously not AT the stupid giant hawks because those birds are protected). It doesn't matter what I do. These giant predators seem to laugh in my FACE! I feel like they're just biding their time and making evil plans for my flock.
They keep getting closer too. I free range my chickens three times a day and then keep them in their large run the rest of the time (we also have coyotes). It used to be that after 20 minutes, one hawk may circle my area from high above. After some time, 2-3 hawks would circle. Next, about 5-6 hawks did a fly over,; and I didnt even know they flew in hunting parties together! Then, I discover them harassing the ladies from about whilst perched on their coop and run. Thank gosh for my run. It is a FORTRESS.
Today, however, while having the ladies do their afternoon grazing, WHILE I WAS OUTSIDE STANDING THERE, a red tail swooped down super close, swooped back up and perched in the trees above my hens. My heart jumped out of my chest. I got my hens safely in their run and carried my 8 month old baby bantam silkie to safety. The hawk was a giant. It watched me the whole time. After the ladies were safely in their run, I threw rocks at the tree trunk to make noise and yelled profanities at the offending giant hawk. Profanities I am SURE my neighbors could hear.
That hawk just stared at me. Like, didn't move at all. STARED ME DOWN. Rocks and all. Profanities and all.
Needless to say I printed out all the paperwork for a US depredation permit immediately after going back inside AND doing about 2 hours of research on what I can and cannot do.
I am a GOLDMINE of depredation legal information, especially for NEO. To heck with these hawks!
