I will tell you what. IF a dog, or coon wants in, and chicken wire is your ONLY defense.... a breeder or hatchery somewhere is going to be happy very soon.
I have a beagle that made a mess out of welded wire, using her paws and teeth. Got right out of the kennel.
I have a shepherd and a Great Pyrenees/Boxer mix that chewed and pawed their way out of a 10x10 chain link kennel. I had to try to re wire it and they destroyed it.
I can cut 40lb fishing line with my teeth.
Perhaps the predators have other options, but if wire snips can cut chicken wire, so can a coon's teeth.
That said, they would have to be determined. I have lost 10-12 in a few days time.
Thanks God for electric fence.
