Hi All So I've been reading threads on electric fences, but they all seem to focus on keeping predators out. I'm interested in the their effectiveness at keeping the girls in. What's to keep them from just flying over? My situation is that I live on ⅓ acre. I like to let them out an hour or so before dark since I know they won't go too far that close to roosting. But I'm thinking if I give them a little space surrounded by the electric fence, that I could let them out for longer periods of time. However, I'd hate to spend the money, time and effort only to have them fly out. Any input would be appreciated. For that matter, any input on options for "limited free range" other than an electric fence would also be appreciated.
