Thanks, Vela. We got a similar space heater for him, it turns off if it's lifted. 8 hours of waiting and $400 later... the Avian specialist thinks he has a digestive problem and is unsure of the severity of it. They found undigested food in his fecal matter. She did a crop swab and everything came back normal. She also found a parasite in his feces. He's on antibiotics and a medication to help crop movement. Draven eats so well and eats every time, but he's "extremely underweight." It's not looking too good for Draven right now, but I still have hope. Thanks everyone for your replies and help.
