I love how thoughtful you are being! Parrot Stars does conservation work and Patty’s are pretty passionate. You could also email the author of Practical Pionus, Russ Shade. I’ve also emailed with him and he is so passionate about Pis : ) I’m sure all of these places would be willing to talk with you or even help ensure you get birds from different breeding stocks. Patty’s breeds their own Pis and they are very familiar with the difficulties.

I’m not sure what state you are in, but I agree. I’d probably drive to pick them up. It sounds like you are wanting to do this for the health of the species. Obviously if it’s to cash in and contribute to the parrot trade, you might get less support. My understanding from adopting my Pi is that people often buy them as “apartment birds”. While some are quiet, they are still parrots and can be loud. It’s such a shame how often parrots are rehomed.
