When we lived in Mexico we bought a 5 week old double yellow head parrot. He had to be hand fed until he was 8 months old. And will they let you know when they are hungry! It was a lot of fun teaching him to talk. We knew he was ready when we heard him making sounds that sounded like our speech. His first work was "Hello!" and whatever variety of that he could think of. We had the opportunity to buy a scarlet macaw but decided not mostly because of the size. A parrot fit our space better.
Your macaw is so gorgeous, I am green, red, blue, orange and yellow with envy.
