I let the dogs out to go to the bathroom before I head to bed and I noticed my silkie was out of the coop and laying in the corner of the run. She's done this a few times, so I went out to put her in the coop and lock them up. That's what I saw the baby possum. I freaked out at first because I thought he may have eaten some of the chicks, but he was just walking around checking things out. Poor little thing was scared. I felt bad for him. I brought him in for my girls to see and then I let him loose in the woods. He STUNK. I guess I'm going to have to lock the chickens up earlier than usual from now on.
