Put up a game camera then you will know what is lurking. Most chicken owners do fortify their coops and runs after they have losses, I have. I don't free range any more due to losses in the past. I have electric wires around my coops and pens, concrete under the gates and heavy duty netting covering my pens all because of losses from predators in the past. When you free range it's inevitable that sooner or later your birds will be discovered and you may have a loss. My losses usually have been from either a coyote, fox or a hawk during the day. At night, coyote, fox, possum, bobcat, owl. I have also had a skunk attempt to dig under a gate to a pen. I haven't had any losses except several months ago, my fault. A fox got my very special bird during the day. I was preoccupied. I should have left her in her pen. Then something got a gate open to one of the pens and killed a couple of birds. I think it was the fox too. It did knock over the electric wire next to the gate so probably got shocked or maybe I would have lost more birds. Since I have put spring gate latches on the gates. I usually only let the birds out when I'm working outside around the coop. All of my coops have very large pens so the birds have plenty of room. I also have several game cameras around on my property and most nights see a predator on at least one of the cameras. Here it's mostly coyotes. Since I got the fox I have seen some but not like I was. I'm sure the one I got was the one that killed my Gladys. I put my live traps out and baited them and let the fox get used to getting the bait then I set the traps and caught the fox. If you have fisher cats and they discover your flock they are nasty little killers. Everything like chicken. Good luck...New flock owner... my babes are about 4 weeks, so they will be moving out of the house soon, and into their coop. My husband has built an amazingly strong run and coop (concrete floor and all), but lately I’ve been hearing more stories from people saying fox and other predators have been attacking them during the day time while they’re out free ranging. At this rate, I’ll never let them out if I’m not there! I don’t want anything to happen to them! Any tips or tricks to prevent daytime attacks? We live a mile from a town, and have houses around. Have seen only cats, beavers, and we’ve only heard a fisher cat once at night. But I’m sure there are fox and raccoons! Ahhhhh please ease my mind!
