I noticed my tarps pulled from the coop, on one end, the past couple days. It's been windy, but I had this hunch.....So today I had Dh move the security camera, to that area outside the coop. He fussed. Let me know there were no tracks, nothing to indicate a predator of any type. It was the wind that was blowing it loose. A couple hours ago, a huge possum, to us southerners, opossum to you northerners, trying to pull off the tarp. I hopped on the tractor, and scared it off. A couple minutes ago, it came back, but scurried on off. I will go scare it off, on the tractor for the next couple days. If it doesn't take the hint, well, I'll go out armed, and it will be fertilizer.
