I currently have nine chickens, and of this flock, I've lost only a couple of unhatched chicks, but nothing that's been running around.
Of all the chickens I've owned over the past ten years, I couldn't tell you how many I've had, or how many I've lost, but as far as predators, I've lost ZERO chickens that I know of to predators. All my deaths were sickness, such as respiratory and Merrick's disease and a couple of other things. I've owned a lot of chickens, but of my current flock, zero deaths.
If you ever have any chicken questions, such as a sick chicken, be sure to post a thread over here on BYC. There's plenty of people over here who'll be willing to help.
