My wife has been preoccupied recently with a job application, and left the coop door open after dark. Now that the days are shorter, its dark before I get home. When I got home I noticed the run door was open, so I closed it up, as well as the door to the coop. The next morning I went to open the coop door, and only one chicken came out. Then I noticed the feathers in the run.. and a few outside the run. Just a handful. No signs of any blood, or footprints, or anything other than the lost feathers. I live near a lake so the Racoons are everywhere, but I didn't think they were such stealth killers. I lost 4 of them, I would of thought I would of found a body or two. Wha'ts odd is that the hen that was picked on the most is the one that survived, maybe because she is always cautious and hightailed it out of there. I can't tell if she now likes her freedom from oppression, or is lonely. She used to never approach me unless I was feeding everyone. Now she follows me around the yard. I think I need to find her a companion for the winter. Is that a good idea?
