Hi! I know your frustration. I've seen one lurking in broad daylight, as well as a coyote another time and also a bobcat. I left my Guineas in for a few days. The good part is, they all three saw me because I went out to see what the dogs were barking at and why the Guineas were squawking. I liked the camouflaged way the one person posted a picture of. People gave you good suggestions, but I have a few ideas to add. I have trouble with traps simply because I worry that I'll accidentally trap one of my cats (which has happened). I'm in Virginia and still running heat lamps, so I've got my limit of power running out to the barn. My barn (coop) is very secure, the problem as you said, is when our pets get nabbed during the day. I think it's great that you have the dogs to help. A couple things of heard of and seen done are to mark as much of your free range perimeter that you can with human scent. This can be done a few different ways. One is human urine. My boy used to pee at a friends house around her flower bed to deter deer. That would be a lot of peeing considering your amount of property. Perhaps a contact with a port i potty company could help. I know that's a hassle. Another human deterrent is human hair. Ask your barber or hair dresser to collect the hair for you and offer to bring them lunch on the days you go get some big bags of hair. Another thing that I've seen done, is human feces was put in knee high stockings and hung from the branches of trees. How they got it in there, I don't even want to think about, but I've seen this at several different places. When you brush your dogs, bag up their fur and spread your perimeter. Ask a grooming salon if they will collect swept up dog fur for you. One person said that the motion light did not work. I have a headlamp for when I take my dogs out at night. They are correct in that the fox doesn't run from just the light. But, if they know you are there behind that light, they do run. They'll stop and look back, but when they know you are there, they give up. It makes me wonder if they make a motion light that activates the sound of a dog barking. But, your problem seems to be during the day because you said that one has not gotten in the coop. I do know, that the sheriff will come and shoot it, but then you have to know where it hides. In my situation years back, the fox was living in a culvert pipe down my neighbors long drive. Because they are high carriers of rabies, the sheriff (at least where I live) will come and try to shoot them. It's worse in the winter here as far as our pets being prey, because the bunnies and so on are hibernating. That leaves our birds for a more visible meal. Then, you have the blasted hawks. I know one tried to get one of my Guineas last week. I was adding perches and saw fairly fresh blood in 2 different spots on the already set perches. That night, I checked them out very closely and saw the damage to one of the Guineas on each side of its body with some feathers sticking out and some feathers missing. Also, there is no leash law where I live, so when my chickens free ranged, they were killed by neighbor's dogs. It stinks and is heartbreaking. I stopped letting my chickens free range. That totally takes away from the "Little House on the Prairie" part that makes the yard come more alive. I also know of someone who bought urine "on line". She had to pass a drug test and snuck the drug free urine into the doctor's office. That's all I know though. You could pee into a five gallon bucket, cover it with a rubber dish (placed upside down) to keep rain out, and when you get enough quantity, start dumping around your perimeter. That combined with the hair, maybe a sludge truck (septic company) will dump on your premises (I have no idea). Thankfully, I work from home. When my Guineas squawk abnormally, I go out with the gun. I didn't try to shoot the neighbor's dog, but I shot close enough to make it go away and it hasn't come on the property again (knock on wood). I'm pretty sure you can get in trouble if you shoot a fox with a bullet, but I don't think you can get in trouble if you shoot them with salt rock. But then, you could sit there all day and not even see it. I also know, you can get a serious fine if you live trap and then relocate the animal. It's like a $2,000 dollar fine. You can also call the game warden, and tell them that this fox is coming out during daylight and you are afraid of it being rabid. Whether it is or not, they are supposed to respond to your call- that's their job. Then, they will remove the trap. If you trap it yourself, they won't pick it up for you. I know this because I trapped a skunk and the warden did nothing because they didn't set the trap. I called a trapper, who would not release the skunk, he would only charge me to pick it up and then euthanize it by drowning it in a creek and of course charge me almost $100 dollars. I ended up getting sprayed- that was fun. I was trying to get a possum, and got the skunk. Good luck to you. I know my ideas are kind of "out there", but it's all that I can think of that hasn't already been said by others. I feel better letting my Guineas free range, because they stick together as a flock and band together to pursue a predator. They went into V formation heading straight towards the coyote. Plus, guineas can take to the air in a heartbeat and fly up very high. They have to be trained to go into the coop though, where the chickens do that by instinct. I hope I have been able to help a little. I know how sickening it is, especially when you see one being carried off.
