I went to open up my pullet house this morning, located inside of my main chicken pen (5 1/2 feet tall 2x4 wire fence, + 6" in the ground), when I found two freshly dug spots in the grass, maybe 3" across, and 3" down. (One on each side of the gate). Thankfully, my main coop has an automatic door (I love it!), and I open and close my pullet house myself regularly, so there were no chicken fatalities... Is it a raccoon? Or is it a skunk? Can skunks climb fences/wooden fence posts? Maybe it's time to put on some barbed wire along the top of the fencing. Thank you for your ideas.
