I'm guessing this is the New Guinea race? I couldn't find much, but a small wiki article. I know it probably doesn't do anything for you. It was all that I could find. Maybe it just goes down to making calls to exotic birders or the importers them selves. That's how I learn what to do with most of my reptiles. I find it better to talk to a breeder themselves, than read a, sometimes, unreliable article. Good luck with the magnificent bird. I hope you keep us posted.
