Got up today to let the dogs out and lo' and behold there was a fox looking at my chicken coop/run. I didn't see him real well but as he ran off the run, body size and tail were unmistakable. I live in the city and in 14 years at this house have NEVER seen or heard anyone talk about a fox in my neighborhood. So what can anyone tell me about how they hunt/kill? Are they fence climbers? Would electric be a good deterrence? Do they hunt during the predawn hours, daytime, only night? How far do they range? My chickens go in a coop at night that gets locked down like Fort Knox. It is in a welded wire fenced run, but the holes on the fence run are fairly large. The coop is fairly coon proof. My concern is for the 11 muscovy ducklings in the run that sleep under the coop and not in it. I may have to force them in the coop at night now.
