I have been freeranging my flock for almost 3 years now on a mountain at 2000 ft altitude with every predator you can imagine, except of course, the ones like fishers that dont live in the south at all. So far, and I do mean so far, I have not had any predator losses. I expect my time will come; in fact, I'm sure of it. We even had a fox's den about 200 ft from the coop and I didn't know it for sure until I saw the little kits come out of the mouth of the den when mama was away hunting. Why that fox family didnt get my birds, I'm clueless. I did find chicken feathers at one of the alternate den entrances, just not my birds'. Most likely the lack of predation here is due to the fact that we are often out with the birds during the day and make many trips to the coops and storage shed throughout. At night, the coops are predator proof, except for a bear, who can go anywhere he wants to go. My property was not fenced during most of that time and now only has the woven livestock fencing around 2.25 acres of it, mainly to keep the girls from roaming across the power line easement and onto someone else's property.
