Hello, and welcome to the forum!
I hope you don't mind me asking, but is there any particularly reason why you are looking to buy a bird? I've never bought a hand-raised baby bird from a breeder before, but I've heard quite a bit from others (especially people from this forum) that hand-raised birds become too attached and dependent on their owners, often not knowing that they are birds. While it is good to have a bond with your bird, it is also important that they know how to be independent. Hopefully someone else will come along and be able to explain this better.
Ever since I found out that there are so many birds in rescues and shelters, I've always been one of those to really support adoption. There are many, many birds out there in shelters waiting for somebody to come along and give them a second chance, having been surrendered by no fault of their own.
