Its aged cedar fencing. It's held up for 5 winters, so I'm pretty confident with that part. It's not predator proof, but I haven't had a problem (knock on wood) with predators when they free range. They are locked up at night.I think you'll be ok with the bird netting and the snow. As long as the lattice holds up. Plastic lattice??? I'm dreading the winter weather and the restriction on my girl's life style. They're now ranging in the garden, with electric net fencing around it, and they're having a blast, but I'll have to pull the electric fencing before the ground freezes. I may put up a basic small chicken wire run for them. UGH!!!
