Sure enough he came back. And what timing!!! I just walked out for the first time about an hour ago and scanned the yard with night vision. I saw a couple of eyes reflecting back at me instantly. It looked too small to be the mink at first but then he started "dancing" and bouncing around and I knew it was him. He was about 50ft from the coop, and being cautious, circling wide into the field. I lost sight of him for about fifteen minutes. I got my gun ready and came back out with the NV and gun (unfortunately not one unit), and sure enough, he was right in front of the coop!
I probably should've continued to observe, but my predator instinct kicked in, and I began to stalk him with the NV monocular (it's 1x so easy to walk with without turning on any lights). He must've heard me because he popped out of the berry bushes to look my way, and that's when I could see him real good because we were only about 15 feet apart. Long story short, I was barely able to flip my gun light on before he took off, and although I sat around for a long time longer I never saw him again.
Anyways, the threat is real, and this totally stinks because my birds don't have a secure run, only a secure coop. I'm hoping maybe I put enough stress on him that he'll be more likely to make a mistake, like rush into one of my traps.
Oh yea sorry so long, but I forgot to mention another bit of drama. I counted my birds and there were two missing! Turns out they didn't get in before the auto door closed, and were roosting on the dang compost box, argh!!! Glad I found them...
