I hunt around 4-6 oclock. From the feather piles I strike from the edge of the thicket as the chickens walk by and drag them a good distance inside before killing them. (2 acre square thicket of cedars, briars and stuff.) I took one full size sumatra roo, and two full grown standard wyadnotte one day and tried to take a full grown brahma two days later. I was scared off when a human heard the brahma cry and I let her go, I outran and outsmarted the dog she turned loose on me. My guess is a fox feeding its young. I dont guess there is any real way to protect my free ranging hens? Foxes can climb fences correct?
