Hi, I'm new to this forum, but not new to raising chickens. I've had a small backyard flock for over ten years but recent events have me baffled and maybe someone out there has had a similar experience that can help shed some light on my problem. In March 2/3 of my flock was killed in early morning hours. Six chickens were killed and only damage was one head missing. That incident was my fault, in that there was a mixup in family communication and no one closed the chickens in for the night. However, just yesterday around 10/30 am in full sunlight, 5 chickens were killed. The bodies were left intact except again, one head missing. I've never had a predator strike during the daylight except Hawks. Any idea what it might be?
