I only have to clip my turkey hen's feathers. She likes to get out and explore and my tom follows her. A couple years ago they got into the neighbor's yard who have a slew of dogs tied out front. I clip ever since. She doesn't learn either. Soon as her new feathers come in, she's out the fence. It's a good acre or so fenced in too but I guess the grass is always greener. I've never had to do it to a chicken. But I don't think it's cruel in any way.
