Predator proofing run - bury hardware cloth or extend it out two feet?

[David 584]

I want to build picket fencing around my bird's run to dress it up a little. Right now I have chicken wire with a treated 2x6 top and bottom. I guess I could lay 24" fencing, heavier the better, on the ground and cover it lightly or just let the grass grow thru it and build my fence on top of it...

hardware cloth is great, nothing can get through it
