I’ve done a few of these and weasel boxes too just making the back a solid board with a bunch of 1/2” holes drilled in them.Unsuccessfully tried some bottom edge sets last year, but everything is froze up right now and I’ve got a spot where we’ve found quite a few mink tracks so my youngest son and I built a couple boxes today. Didn’t have any hardware cloth or chicken wire and needed to honor the edict my wife made about not buying any more stuff for trapping this year so I used landscape fabric for the back. Hopefully will still breathe and allow the scent of bait to come through.
