❓❓❓ What kind of wire-mesh to use for a duck-run ❓❓❓

as further enforcement against digging predators the inside of the floor will be lined with 2x4" welded-wire mesh (just have some of that stuff lying around here) and the edges will also be filled up with gravel:

I guess that should protect against most smaller predators - we don't have bears in the area!
