Stoats are similar to minx and ferrets, however predatory wise they are different, stoats/ferrets/weasels can't and won't do the damage a mink can do and does, nor are they anywhere near as ferocious as mink. Mink don't live in the area where I am thank goodness. I don't claim to be an expert however years ago we used to keep ferrets so I am aware of the damage they can do, weasels/ferrets/stoats won't try at the ducks now they are too big and in a couple of months they will no longer be a threat to the chickens either - it is very rare although not unheard of for a stoat to attack a fully grown chicken or duck, they will however try at growers. Mink kill to drink the blood of the animal but won't eat the carcass, ferrets/weasels/stoats kill to eat, ferrets and weasels don't opt for prey bigger than themselves stoats however do but is highly unlikely and practically unheard of for a stoat or any of these to attack a fully grown chicken or duck - the mink however does. The videos does not show the thickness of our wire, I have no idea why it looks so thin on the video but I can assure you it isn't and it is adequate for what we need here in the area I live. Our biggest threat is foxes, and hawks.
