I have a very wild yard with woods attatched and also have always chosen darker chickens, reds, barred, EEs in darker colors, etc for just that reason (predators). I've lost very few to predators or cold, (knock wood) and attribute at least some of that to choosing the right birds for the place I live. Since we have damp cold winters, I go for smaller combs too. This spring (late winter) I hope to get some Buckeyes since they are bred for this very climate.
Just give up trying to control your chicken addiction, enjoy yourself since in the grand scheme of addictions, it's a pretty darn harmless one, and actually, pretty darn healthy really. There's a lot to be said for caring for creatures that depend on you to help you care for yourself!
