Hi HungDou, I am in HK a couple of times a year, and always go to the bird street meetings on Sundays, I am sure you know about those. Iff you could enclose your outside deck that would be a great 'cage for your macaw. I see many many apartment decks with full bars on them in HK ( due to people climbing up and robbing) so that should not be an issue. If you get him a play stand for inside, do not leave him alone on it, macaws can be very destructive in chewing up everything and may chew on an electrical wire or outlet. DO put him an inside playstand as soon as you get home. You could make a cool one out of PVC plastic piping, vet tape, and wood branches, for little money. With more toys ( the chewing kind) your macaws beak will start to look better over time. But it will be hard to put enough toys in his small cage to keep him busy all day. Try to figure out the kind he likes and get several variations of that, so you can change them out often - it will help keep off the boredom. If he wont play with any toys, play with them yourself and let him see how much fun they are. You may feel silly but parrots do look to us to see what is fun and what to eat. At 1yr old I would think his beak and crop are developed enough to handle cracking open nuts. Not too many though! Let your Avian Vet tell you if his beak will take the stress in his current condition. Leaving the TV or radio on is a good idea - parrots can actually see digital flat screen TVs , unlike dogs an cats.
