I put together a video to demonstrate just why we made sure our chicken yard was very secure... The images in the video aren't new, but some of them are new to YOU! *grin*
I use a Leaf River trail camera to see what kinds of critters visit the chicken coop at night. Here are some images and video clips I've captured, of unwelcome guests at the chicken coop. The wire around our chicken yard goes all the way to the roof. While it may LOOK like there are gaps in the wire, that's only because the wire doesn't show up in the video. The covered (roofed) chicken yard is 10x10, and connects to a larger (uncovered) 30x40 yard. I shut the gait to the larger yard at dusk, to ensure no predators can get into the chicken house, or into the covered yard.
If you have trouble viewing the video here on the blog, you can check it out on YouTube.
