Electric poultry fence experience? Predator protection?

Hello fellow chicken enthusiasts! I’m reaching out to tap into your cluck-tastic experiences with electric poultry fences. As I work to protect my beloved hen-only flock from sneaky predators like coyotes and bobcats, I’m eager to hear your insights and feedback. I’m just getting started on this feathered adventure and would love to create a safe, free-range environment for my girls without the need for livestock guardian dogs or donkeys in the near future. If you've successfully used electric fencing to safeguard your chickens, what tips and tricks would you recommend? Your shared wisdom would be egg-citingly appreciated as I navigate this journey in Western North Carolina. Thank you in advance for any advice you can share!
