I went out to lock up my chickens tonight after dark, and i heard something scatter through the woods. it sounded small but lumbery. I figure a cat would be more light footed? I have never had a problem with walking predators, would a raccoon just show up all of a sudden? i did just move my 6 wk old babies out to the coop a few days ago..... If it is a raccoon, am i pretty much screwed? My pen is not fort knox.
