I'm not in West River, but this past summer I had one continual Skunk visitor. I also had a massive problem with raccoons. The skunk was not too troublesome since my hens were put in each evening into a coop that he couldn't get into.
However the coons were horrid. Before I fortified my coops, they wiped out over 30 birds, from ducks, to chickens to pigeons. The skunk was mainly after the grains in the feeders & the eggs. Mind you my skunk problem is amplified by the fact a neighbor FEEDS the skunk on purpose from a cat dish on the porch, so she can WATCH it from her window!!!
So I started putting out a ferral "cat feeding station" out on the very egg of my property, along the skunk's nightly route.
I also noticed a different in digging patterns between the coons and the skunk. The skunk will dig maybe three inches but the coons dig all night if they have to. I was told that since the species are both territorial, trapping them only means you get a new problem later. So I had to "teach" the critters it wasn't worth wasting their energy at my coop.
I tried the repellant stuff (it didn't work). So I resorted to some other tactics. I drove rebar into the ground along the edge of my coop. It went down three feet into the ground. They can dig all night and get NO food (eggs or chickens). Before two weeks were out, they started going elsewhere to find their dinner. I also used the bull nettle and thistle stalks I was fighting to cut down (at the edge of my property & that of my neighbor's) as reinforcement. I took the thorny plants and carpeted the paths and parameter of my coop (other than where the hens enter) with the cut down stalks. This means they predators have to walk on the thorny stalks to go to the hen house! That worked very effectively to help "educate" them on why my place wasn't the easiest banquet hall.
Every once in a while I seen signs of the skunk, when I forget and shut the gate to the pen (feeding troughs and water), but other than that I've had no more predation.
