My budgies recently got their wings clipped. They all seemed fine right after. However, a few days later, one of them keeps stretching her wings, especially the right one. And whenever she stretches it, it vibrates. She tends to keep it stretched and therefore, it continuously vibrates. The wing area that I would equate to the human shoulder also seems a little higher on that side than the other. Is this just a stress response because she is the one that is least comfortable with touching and loves to fly away from us (and now she can't) or do you think there's a problem and she hurt herself trying to fly after getting her wings clipped? Her behavior seems fine and she seems to fly and jump around like normal.
