The last couple of days I've been losing chickens. It started when I finally started penning them up at night. I heard a squaking went out in the middle of the night and didn't see anything. Figured they were being testy. In the morning I was missing 3 chickens, I only found one dead. It looked chewed around the eyes and legs. That left me with 7. This morning I went out to let my Jack Russel do his business and saw feathers all over the yard. Now I am missing all but 1 and found 1 dead. Same MO, but this was in the middle of the field. Any ideas before I set out tonight with a shotgun?
