I'm sure this has been addressed in several places here, but when I read through the posts, I get mixed messages, so I would like anyone who knows something about this to chime in here:
In December our three hens were killed by what I believe was a weasel or mink. According to the MN DNR we have short and long tailed weasels in this area, as well as mink. The coop was far from "predator-tight;" there were several holes that were over 3" wide. This time around I want to weasel-proof my coop. Even if that's not the animal that killed the hens, they are around here so I want to make sure they can't get in. I am also building rabbit cages (I'll be breeding rabbits starting in April).
From what I gather, hex poultry fencing (i.e. chicken wire) is not strong enough to keep critters like raccoons out. They can pull, stretch, or chew the holes until they can get in. I'll use the same thing on my rabbit cages as the new chicken run. I bought some 16 guage 1x2" galvanized welded wire mesh. This is the stuff that most rabbit cage instructions call for. This seems small enough to keep out anything down to a short-tailed weasel. But before I invest the time any money, does anyone think I need to go down to a 1x1" grid size? It's a bit more expensive and comes in smaller rolls, but if it's going to prevent a total livestock loss, I would gladly pay it. Opinions?
