Happy Thanksgiving to all. Wanted to post this question to anyone who can answer. Kit appears to be getting healthier. she is getting more vocal since Pixie has come into our household and i think she is feeling more vibrant about life since he is here. Pixie is a yellow naped amazon who was in NH and in need of a new home. I was wondering since Kit is starting to appear like she is feeling better I notice her Feathers appear to be brighter. Do their feathers change in hue and color when they are healthier?
