Here is the mink that killed all my laying hens last month. Killed my 10 girls that had only just started laying. Ripped all their throats out. This happened about 10am on a sunny day. It was still going through the nest box when I got my air rifle and ended his killing spree. I live in an area that mink farming pretty much supports most business one way or another, so raising poultry can be hard. This was the only visit this year although one "accidentally" ran under my truck while driving a few miles from home.
