Same here. I haven't talked to her recently, but I did a number of years ago and she was very transparent. I don't think I was asking about buying a bird though. I had some other questions I can't remember that I was doing research on. Actually, I think I called asking about feeding response and weight gains in yellow nape babies and we got into a discussion on breeding and hand-feeding practices. I was impressed that she seemed to be quite attached to her breeder birds which a lot of people aren't. I think their bird's might be toward the high end of price, but probably a better breeder than some random person that doesn't put much thought into their operation.
Also, remember to ask about baby's personality. If there are multiple babies in the clutch, as how their personalities are different or how this baby compares to other red bellies that they've raised. Sometimes you get a clutch where they are all sweet and pretty similar and other times you get one where a certain baby is more snugly, another more adventurous and another more fearful.
