Had my first bear attack last night.

Last night around 9pm my wonderful Pyrenees, Miss Pearl alerted me of something. I grabbed my spot light and shined the coop… It was completely flipped on its side, the door to the enclosure was ripped off at the hinges and tossed like a rag doll. I grabbed my rifle and began expecting the worst, fired several shots to make some loud noise. Sure enough a bear goes running off into the woods. While inspecting the coop I saw all my girls huddled together in the nesting box, didn’t lose one… My god what relief.

What do you fine people do to alert yourself of predators? I’m considering hanging goodwill pots and pans around the enclosure to make noise. Any help? Thank you 🙏
