Do they ever sell large macaws such as greenwings or blue and golds?

Yes, hand raised, basic training. Wonderful companions when released to new homes.

Yes they have all types and allow people to sit with and hold most of their birds

Yes go check them out.

They do. You have to get on a waiting list though. They will give you a call when there is a bird available.

They definitely sell blue and golds. I don't think they're a bird that they would regularly have, unless you had personally already shown interest for one.
