I waited too long to go lock up the chickens!! I was busy watching ti.v. and waited until 8 o'clock and never should have waited that long. When I got to the coop there was a racket going on and chickens starting to flee the coop, I ran around to the main door and there was a possum in there and one chick dying on the floor. I threw a heavy steel half door at the possum and was screaming for my dh the whole time. My dh ran out the same time the possum ran out of the coop and my dh picked up a metal fence post and hit it over the head but it still got away. I will be sitting out there with the .22 waiting for it to come back! I feel so badly for my poor chickens. It took awhile to round up the other chickens who had fled the coop and then I pet each one in the coop trying to settle them all down. Poor things, it was all my fault. I will never let it happen again. Warning!!!!!!!!!!!!! Predators come out at dusk!!! Let what happened to me teach everyone a lesson, please!
