I have a Golden Pheasant that was a cruelty seizure that the SPCA placed with me several months ago. He lives in a 10 X 10 X 15 (high) aviary shared with three little Silkies. They seem to coexist and I have never seen any one pecking him. He gets game bird food along with kitchen scraps that he shares with the silkies (lettuce, tomato, grains). He also snacks on their food, which is a mix of poultry chow, scratch and layer pellets. The last week he has started to look terrible -- really rough feathers like he's been wrapped in a blanket and rubbed the wrong way. Today he lost his longest tail feather. He's by nature very skittish and spends most of his day pacing on the south side of the aviary. We have a multi-branched tree in the center for perching and when he is not pacing he perches. So, is he molting? Physically sick? Mentally or emotionally unstable? Do I need to take him to an avian vet ASAP?
