It's time for another session of CSIoultry. Maybe you can help me determine what killed my hen. This afternoon about 2pm my kids went out back to gather the eggs & let the layers out for recess when they found a dead hen in the yard by the chicken pens. Her neck was broken, there were a few small puncture wounds on her back, but otherwise she was intact. Nothing had been gnawed on or off. She was lying on her side, one side was matted with mud from the rain-damp ground. My first suspect was DOG. Daytime attack, broken neck, nothing eaten off. But there were no paw prints (the yard is loose dirt & mulch) and no trail of feathers that usually indicate a chase before capture. So my other suspects are the 26 young cockerels that free-range all day throughout the yard. The oldest ones are around 18-20 weeks and I guess would all like to get "married". Could young cockerels kill a hen in their efforts to mate with her? She was a grown standard-sized hen, but these guys are all her same size or even larger. Has that ever happened in your flock?
