Possum I have ever seen in my life!!!! It had to way 15lbs!!!! I just got home from work and I walked in my my coop to check on the chickens since it has been so cold. Well there in the corner of the coop was a huge possum!! I carry a pistol with me in my truck and happen to have it clipped on my belt since I had just gotten home. He ran out of the coop and hid under some wood, but I got him!!!! I think he was just after the food, but as big as he was, he would have had no problem taking a chicken. And that would have made me really angry!!!
