I got home about 10:00 tonight, found out that DH hadn't had a chance to shut the chicken coop in the barn and went out to do so. The dog went with me as always, going into the barn ahead of me (this always makes me a little nervouse since I don't know what he's going to find - really don't want him surprising a skunk!). When I went in with my flashlight, he was sniffing the air and on alert. Shined the light into the coop, and there was a possum! Dog went in after it and got it out of the barn. It was a younger one, not nearly as big as the one in the garage a few weeks ago. Anyway, it won't be a problem anymore.
