What do you think might have killed one of my male Indian Runners? They were out by our pond, I found it with the head on, but the neck and back had been eaten. There were feathers about 3 foot all around the body. Could it have been a hawk or owl? It was during the day. I keep them in a coop at night. If it was a hawk or owl, how can I protect the birds while they are out? I will be keeping them in the pen for a few days.
