Gosh I really agree with this. Phoenix got way too attached to me, I was lucky that I was able to spend 12 hours a day with him so he didn't start harming himself or becoming depressed, most people can't really do that. I had to get Phoenix another bird, and I'm currently weaning him off of me. He's much more independent, now. I wouldn't say our bond is anything more than what most people have with their beloved, bird-raised petsHand raising birds imprints them on people. I personally think it's immoral. The results of such experiments have been known for decades - they ought to be in the no need to repeat them category. The birds become sexually frustrated as people reject their amorous advances & to top it off they reject the hand raiser (who wants to date their parent?!).
If you chose to get a hatchling and raise it, it won't be your best friend forever. It will grow up, and (hopefully) learn to be independent, and that's if you're lucky. If you're not so lucky you could easily end up with a depressed bird, leading to illness or even death.
You have a better chance forming an inseparable bond with an adult parakeet because they are already grown up, you know what you're going to get, and they won't grow out of you.
It's so much better to get an adult. Why don't you check out some rescues? There are plenty of birds there that need a hero, I'm sure they'll thank you for it
