Exactly my thought too. It's common sense and gut intuition here as most of us do with many things we buy. I think the most valuable information you will find is this board and it's members advice or past purchasing experience(s).There isn't a right or wrong answer to this question and each person is going to answer it differently. I think there were a number of great questions to ask and you'll have to sort out which ones you think are most important to you.
Some of the basic questions I asked were diet, what they were weaned onto and allowing them to be flighted.
I didn't buy my parrots to be shipped to me, I went to where they were and saw how/where they were raised so I had a choice to either take my baby or decline. I was fortunate to find breeders within reasonable driving distances.
Birdbreeders.com has many breeders listed with ratings by those who have purchased from. And I found both of my birds on this site.
