It is predator proof for my area. We don't have desperate predators, but I double wrap it as a precaution. The design of the run would work with hardware cloth too, so if somebody wanted to switch it they can.Chicken wire is not predator proof.
I believe "predator proof" varies by area. Predators around me have plenty of food and don't want to waste time ripping through wire. And I definitely don't have anything large like bears around here.
So if your opinion predator proof is different from mine, so be it. I know the chicken wire can be a bit topic, but please, I don't want to be involved in an argument.
