We have a flock that has lived in my neighborhood as long as I've lived here, 6 years.
They are the ugliest things around! We hear them gobbling all of the time. Only once, did I see one attempt to fly. It looked like a very unstable helicopter going up to land in a tree.
For a couple of years they stayed down from our hill, on the farmland about 1.5 miles from my house. It's like they come up here for their daily walk.
