Oh, they are quite agile. Mine roost in trees if I don't bribe them into the coop before sunset. They fly over any fence and onto the roof of my house just for fun. I free range my flock, and the grow out cockerels are in the orchard. Still free ranging, but it's an acre of trees surrounded by 8 foot high deer fencing. The cockerels can easily fly out unless I cut their wings. One can get out even with cut wings -- he runs at the fence and flaps his trimmed wings mightily as he walks straight up the side to the top cable, then glides down gracefully. Today I saw one of the 3 year old hens easily fly onto the top cable, walk along it like a tight rope walker, hop up to the top of the 9 foot tall 4X4 post, then roost up there surveying her kingdom. Luckily they like where they live and don't leave, because they can fly almost as well as my heritage turkeys. Yes, quite an agile breed in many lines. Other lines, I'm told, don't fly much, which is good for people who want to free range their birds but can't have their birds leaving a fenced yard.
