Hey
frogman
I am not sure I will have the answer for you but I live in the suburbs and have 6 bantam gals who fly like bricks and only get to free range under supervision because of neighbourhood dogs and cats.
While we have fences around the back, one of which is only very low, there is the option to wander up the side of the house and out into the front garden but in over two years, my gals have never ventured out the front or tried to jump the fence.
One reason I believe this is the case is that the matriarch of the flock was never one for wandering and she has probably passed this down to the others.
Another reason could be all the ‘fun’ places I have for them to dig, explore, hide and ‘play’ in the back garden.
They have lawn; their own garden beds specific for digging and dust bath spots .. there is also a decked gazebo where humans dole out meal worms
As mentioned, free range is supervised every afternoon for a couple of hours and the majority of the day on the weekends.
May be, if I was not watching them, they would wander out the front but I think having me pottering around outside with them keeps them close. Also, they seem to like to keep their coop and run within sight.
