So I've not yet started my chickens... I own a 7 acre lot with other similar sized lots in the area. I really want to freerange my chickens... I've seen some tall fences (7' or so) of chicken wire at our local farm... I was wondering if I built a wall of fence somewhat close to the coop, and then had the coop inside with maybe a top or higher entrance, would chickens be able to jump the fence in the evenings / on their own and enter the coop and still be safe from foxes. I assume foxes cant climb vertical fencing? or is this wrong? My goal with this idea is that if a fox comes and the chicken is semi-close to the coop/fence they can fly up over the fence and be safe from the fox... If I have 20 + chickens, the fox might get one or two but I'd assume that I'd have critical mass to survive fox attack?? thoughts? Am I giving too much credit to the chickens here?
