My parents’ sole surviving chicken from their old flock

Mocha is their six-year-old barnevelder. Still very occasionally lays eggs but she is otherwise spending a quiet retirement in my parents’ backyard. More surprising is the fact that she seems to be doing just fine living alone? She’s been solitary for almost two years now and spends most of her time following my mother around as she does yard work. Unfortunately, she still doesn’t really like my wife and flees in fear whenever my wife is around.
