I keep my girls, Barred Plymouth Rocks, in a large coop with hotwire around it at night. I have never had any problems at night. I started with 15, 3 years ago, and only lost a few in that time. Now in the last 10 days, I have lost 7 girls while they are free ranging in the afternoon. We have about an acre and a half of cleared yard surrounded by woods. We have part of the woods fenced in with electric fencing for our 2 goats. No problems with the goats so far. The rest of the property is not fenced. I have been home when most of them were taken, with my 2 big dogs inside with me. I heard nothing, nor did my dogs. One I found of my girls in the yard with a bite to the back, looks liked she had been chased and carried by the feathers. I assume a dog? The rest of my girls, it seemed like one a day, I followed feathers into different areas of the woods to find their headless bodies? In the past, I have seen 2 of my girls killed when hawks pounced down on them and ate the neck and heads, but all feathers and body in a small area. These attacks were very far apart timewise. I am confused about the time of day of the attacks and, it looks like they are being chased and carried into the woods, but only the neck and heads are gone? I put out my wildlife camera, and tried to keep vigil during the day while the attacks were happening, but I haven't seen or heard anything. Now I am down to 2 girls, that I am keeping cooped up until we can build a covered run. Any Ideas?
