I came home from an errand about a week ago and my neighbor told me they had spotted an opossum in my backyard. I looked up and the ugly little critter was looking at me through a gap in the fence in my neighbor's yard. As we were talking, the opossum strolled across the fence and went into my yard. Broad daylight. About 5 pm. This animal was not in the least worried about two humans standing 20 feet away. He strolled down the fenceline and went under some brush in my backyard (I have since cleaned that out). I took a big stick and went over to chase him off. Rather than run away, he bared his teeth at me. It scared my little dog who was with me, and I wondered if this opossum was rabid or something, so I went on in the house. I have not seen him since, but we are getting ready to fence in that part of the yard for the chickens to run in next week. Are they going to be vulnerable to this critter? Should I wait longer before letting them out? Has anyone had experience with opossums in the daytime?
