Sounds identical to my last attack. Tarps pulled down and chewed. Wire mangled (2x4 welded wire, bent, not broken.) Tons of slobber and some blood below where the wire was gnawed. NO ENTRY MADE! WooHoo! I had a game cam and rushed to see what I would be tracking down to kill - answer - my own dogs. The dogs will not even look at the chickens when they are out free ranging but nature got the best of them that night, and what with all the squawking and flapping (the bedding inside was covered in feathers where they were obviously hysterical, poor babies.) I bannished my dogs to their pen - now they only get out when we are in the yard to watch them. The guineas will sit on the top of the dog's 5' chainlink kennel fence and scream at them! LOL The dogs sit and stare up at them and wait on one to come to dinner. Dumb birds. It's scary but gratifying to realize that something tried it's best to reek havoc on your birds and your planning and prep was good enough to stop 'em! Congratulations! Well done!
