I lost 9 in a afternoon to a fox. I had let them out in the morning when I went to work. Everything was fine at 10AM, when my wife left for work. Daughter got home from school about 1:30PM, to find piles of feathers all around the yard. You could see where the fox got each one. I looked all through the woods around the property, found another smaller pile of feathers. The chickens were just gone. I've seen this fox a few times since. The thing with the fox is, he won't take just one, like a hawk, he'll take them all. I have a large box/ live trap. I read on here that sardines were a good bait. That led to a couple less coon around here, but not the fox I want. I had a shot at him last week, but missed, got impaitent, should have waited for him to get closer. I'm going to try a raw chicken leg in the trap, and see if that works. I know that fox has really cramped our style around here as far as the chickens go. We used to let them out early in the morning, let them wander around and do whatever they wanted. Now they get let out later, we try to keep an eye on them. We went almost a full year with no problems, now we got this thing literialy stalking the birds. Good luck getting that fox. Cause if you don't get him, he'll never go away.
