It is a travesty to see
hand fed birdies being offered as if that's a magical mantra for birdie companion. In addition to offering of unweaned baby parrot with the innuendo that having unweaned baby parrot meant you can impose yourself as a caring mom/dad to be rewarded by birdie love later.
Even wild caught birds, and old birds, can be loving companions when you treat them with respect and courtesy due to another intelligent sentient equal to you.
I have very dim view on 'hand raising' of birds in addition to offering of unweaned birdie for sale.
That deprived the little birdie on proper interactions with its parents and designed to hopefully 'imprint' on it that he/she is a human. Are we that incapable of understanding and training with a bird that we felt compelled to rip a baby from his/her parents?
This lead to the marketing and selling of birdies thats not weaned. Perhaps better the profits to the breeders, but is that a better life for the birdie?
Or is a perceived easier life to us the only thing that matter?
Of course, claims of 'handraising' sells especially to people who do not know and wanted something quickly.
It seems too that handraised birdies later on developed serious psychological problems.
The sad part is even older birds, and birds caught from the wild, are really trainable.
Riamfada was a wild caught CAG as seen in her open leg ring. She was a rescue and given to my charge when she was about 5-6 years old. She came to me bitey and fearful.

In about a year, she was doing free flights to me.

Yingshiong above is a white rumped shama. A shama is a songbird. He was caught from the wild at about 3 years old. He was given into my charge at about 5 years old. He flew to me on cue within a month of coming to me. Breeders of shamas told me even their breed shamas , some they hand raised, never ever landed on them. They told me above was the first ever they seen of a male shama landing on a human.

Libai is a Greater Greenleaf song bird. Caught from the wild and probably about 3 years old or so when he came to me.
Many problems cropped up later when such birdies reach adult hood.
