Help with weasels!!

[chickie farmer]

I use 1/2 " hardware cloth completely around my run and coop. buried about 10" deep. and a little over 2 ' above ground. plus at the run door opening, I overlap the poles to make the openings around the door as small as I can get it, to keep small critters from getting in. plus a cement block and a half JUST under the door. I have woods beside and behind me and I haven't had any trouble yet. knock on wood.
