Try a humidifier, not too close to his cage. A flight suit to stop him from plucking, because even if a humidifier does work he might have developed a habit. If you are handleing him do not have the suit on him. Are you using bottled water? Preferably spring? I would suggest this especially in a far flung place like Croatia! Things with natural oils such as pine nuts, peanuts, even a little peanut butter from a spoon held by you, but not too much ... scrambled eggs with a little milk and butter. Sounds like his skin is dry, as it gets when you go skiing for example and your nose dries and bleeds ... skin gets dry, lips crack. Very painful! Has he had any change in climate? evan just a change in houses? If you think about the fact that where they originate, its pretty humid. I have owned two and had many friends who have also .. no plucking complaints, but we have lived in very humid places like Singapore, Dubai, Texas. Good luck, I would love to know if this works for you at all. I am no expert, just a Grey owner and this is what I would try. Lisa.
