Hi, My severe macaw has had some changes in his feathering. There is what seems an abnormal amount of feathers are coming in brown. As a little background in him he is around 15 years old, and was on Meloxicam in the last few months due to an injury to his foot. Has anyone seen anything similar to this or know an explanation for this change of feathers? How his feathers look now... Dropbox - now.jpg How they originally looked... Dropbox - before.jpg Thanks!
