Norm, Welcome to the world of pesty pests. Here I have chickens and our possums are a major problem. I have already relocated 4 of the beasts last month. They are digging into my barn and killing my chickens. At least they only kill one or two at a time, unlike the mink that was killing them and piling them up. It killed 11 chickens twice before I caught him and terminated the pest. Smart little weasel relative, he keep tripping the steel traps but couldn't get the live animal trap though it wasn't for him trying. He was bouncing the trap al over the place.
I even had a Raccoon killing my chickens but that apparently didn't agree with him as I found him dead in front of the barn. Boy did he leave a big hole in the side of the barn where he chewed his way in.
Wish you luck on scaring the pests away though the owl hooting might cause the dog to bark too.
