lake PARROT OWNERS help fast please!!?

We have observed that my quaker parrot is picking at the feathers around its feet, and we were informed today that she is beginning to pluck her feathers. I know that it is from stress, and I really want to help her before she engrosses herself even more in this behavior. As of now it shes not missing a lot of feathers, but I know it will incline if we do not do anything. Has anyone had this problem before, and corrected it. I have given her tons of new toys and they keep her occupied and I have been staying in the room, and talking to her quietly to distract her from plucking. It has been working, but I can not stay with her 24/7 but she does get a really good amount of attention from about 4 other family members. Please tell me about your experiences I have read just about everything on the web. Any information about how to stop this behavior would be really appreciated. Thanks in advance.
