We have a young possum living under our deck in the backyard. Usually, he only comes out at night after the girls are asleep in their coop. Today, I threw a big juicy tomato out for an afternoon treat. I looked out a few minutes later and the possum and our small flock were at a standoff over the fruit. The large red sex link, Gertrude, chased him soon after the photo was taking, trying to bite his tail. He stopped, hissed and bared his tiny sharp teeth before disappearing under our deck. No one was hurt. The chickens calmly went back to their juicy snack. Chickens 1 - opposum - zero.
