In case you couldn't guess, these are more pet birds than livestock. My brother raises the chicks and sells the eggs, but he also names them and socializes them so that the sight of even a grown chicken perching on his shoulder is not an unfamiliar sight. A few have been trained to fly to his arm and some have been known to fly onto his head as a greeting when he steps into the chicken yard. It all starts with the handling they get now, when they're small, so that even the few roosters we've had have been friendly instead of vicious.
It's not exactly hard to spend an evening on the porch getting to know these handfuls of fluff and feathers.
