Glad to hear you are making improvements already
Just remember to be patient... All going well he will live for 30+ years so a couple of months for taming is nothing...
However, I have had a thought, if a bird is not chipped or banded, how can you prove the bird is yours?
If you then want to get it chipped, what will they ask as proof?
And out of curiosity, which breeder did you get him from?
