We've had our chickens since April. We think a fox just discovered this fact. Our chickens have access to their run from the coop from around 8am till I'm done with work, around 6pm. In the summer and fall, it was still light. Now, it is dark by 5pm. At 6pm, I went to tuck the girls in and lock up the coop, but came up short on the head count. I found one of my BO dead in the run, belly open. I could see tracks along the run where an animal, presumably a fox, paced several times before climbing the run fence. We have no netting on now due to the snow. (our mistake) We're thinking of running an electric fence wire along the bottom at 6" from the ground, then again around 18" up. With winter snow, will the bottom wire short out? Should we just place the wire higher than we believe the snow will get? I'm afraid now that the predator has found an easy source for meals, it'll be back! I'd like to get the fencer installed this weekend. Thanks for any input.
