Full moult to adult plumage? Or just a few flight feathers?

My fhh is almost 6 months old and has now dropped 4 flight feathers over the last month. The 3rd dropped 4 days ago and another this morning. Her weight is 896g and she's responding well. Never had a bird moult this early before so I'm wondering if this is just an early partial moult or if she's gonna through a full cycle and change into adult plumage. Any thoughts?
