To all who responded about my Grey and the ultra sound pest controllers. She really is back to normal, she isn't unsteady on the perch, she is holding her food again, and her appetitie is back. Before I removed the sound plug ins, she was afraid to eat with one foot holding on and now she is even dancing again, keeping rhythm to the music. She had really shut down normal behavior until I realized what could be the problem. Again, my other little parrot did not seem to be effected and my dogs and cat are fine. At least the emitters don't go through walls, supposedly, so if I need to use them I can use them in other parts of the house. I'm very relieved that she is doing better and that I have some forum friends who have given supportive communications.
