You are raising a child monster with permanently-affixed pliers, and that child is gonna be a two-year-old for fifty to one hundred years, depending on the species.
Every mistake you make in his or her formative years, every bad habit you instill, will be with you for the duration of that parrot’s life.
It’s so important to do your research. Any bird, big or small, requires a level of expertise in handling and training beyond that of a cat or dog. Negative reinforcement doesn’t work, and it takes a measure of patience that many many not expect.
Baby parrots never forget, and they rarely forgive–and only if you grovel. 😉
This is just one more reason why I strongly believe in adopting an older bird. If you spend enough time with an older bird, you know what their quirks and habits are BEFORE you bring him or her home, and if you make a few mistakes here or there, you will not be imprinting key memories in a bird that is as impressionable as a baby one.
