Not necessarily. What I will recommend is having each family member spend time near her speaking softly to her, even singing sweet nothing tunes and hand feeding treats. If she pins or ruffles her feathers, that's her queue she's uncomfortable with their proximity. Taking a step or two back will oftentimes resolve the discomfort.
It's all about patience and learning to read their queues as to what makes them uncomfortable and then respecting it. If we push our agenda onto a grey, be prepared to have it declined.
