I don't think it really works. I had an issue several years ago and a skunk was digging under the gate to my chick/grow-out coop pen. I had forgot to shut the pop door and it was closed just enough that some of the chicks couldn't get inside and when I realized it I went out and there was a skunk attempting to dig under the gate to their pen. I stomped my feet at the skunk and it turned towards me and stomped it's feet at me. I went into the house and got my gun and went back out and attempted to scare the skunk off and again it stomped it's feet at me, it seemed persistent. I shot it and put a bucket over it until I could deal with it in the morning. I was able to let the chicks in their coop.Finally my two boys and my husband have an excuse to pee outside! Definitely will try that. Wondering how to facilitate hot wire without harming the ducks and chickens?
