Yes BP I am aware of all those factors these guys do not seem to be a mated pair they mostly ignore each other they are sharing a Macaw size cage here at our home but shared a smaller cage before they ended up here (temporary guests that have been here over a year now). they were already plucked prior to arrival and they have improved somewhat during their stay. Aloe baths could be more frequent as that seems to help the most, but it is cool by the big windows so limited until it warms up a bit. Cage is stuffed with things to shred, chew, climb and take apart and I have improved their diet as well they were big pellet birds, now fresher stuff for them. They are eventually going back to the "owner" so I can only do so much. Have had several pluckers and a mutilator or two through here so am always looking for new information on diet and behaviors. Right now we have a Cockatiel and a Senegal in the guest bathroom during their recovery from in the Tiel a wingectomy due to bone cancer and the Senegal manged to get a severe burn from a heat lamp after recovering from a beat down from his flock. Happy to tell you they are both doing very well, never a dull moment here.
