Well I do have some answers for you!
I didn't know that she was selling someone else's bird. I didn't find that out until a week after I bought it. She never mentioned it, just had it on her sales list under her own name. I'm sorry, but if you're NPIP, can't you get in trouble for selling other people's birds under your name? What if she's brought in a disease into her property, now? Regardless of if it was hers or her friends, if you're selling something under YOUR name, then you are taking responsiblity for the sale and for the health and condition of the bird. (I'm not saying the bird's sick, it appears healthy to me, but I'm just making a generalized statement).
As for the breeder's reputation, she allegedly IS a reputable breeder! She's a big name, quite a few people know who they are, they're NPIP, so that makes me feel that they should have good, healthy, quality birds.
And as for the price tag of a mere $20, I have an answer for that, too. Yes, I did think that was a little on the low side, but I certainly would NOT have thought that it was due to it being a mix. Any dealings I've ever had w/her inthe past she has only ever sold purebreds, why should I think this one random bird in an isolated insident wouldn't be a purebred as well? {{shrugs}} And she and I have talked about the rediculous price that some people have on their birds. Case in point; tolbunt Polish. There are a lot of people out there asking $60, $75, even $100 PER BIRD! And when we were talking about it, she said she's trying to get into them right now, too, and that when she gets established w/them she's planning on keeping her prices reasonable. She said she was only going to sell them for $40 a pair! So....naturally....even though I sure did think $20 was cheap for a sebbie, I just thought she was trying to keep her prices reasonable and competitive.
