You are more than welcome. If I've helped any at all, I'm glad.
Yes, time and patience can be the answer to most parrot issues.
Especially rehomed and/or previous breeders. A couple more
suggestions, based on this last info. Be careful about subjecting
them to sudden temperature changes of more than about 10 or 15
degrees. For example, if you keep your house at 70%, it's not good
to put them out when it's over 85. And yes, access to shade is
critical. Also when putting them outside, we have to be sure they
are protected, not just from the obvious predators but also from
mosquitos. Mosquitos can carry the West Nile virus. Humans can
survive it, parrots, not likely. We also have to stay aware of all
the air borne diseases and the parasites carried by wild birds. If
wild birds can get droppings inside their enclosure, that can be
bad. If you are in an area where there are Hawks and other raptors,
you must be careful of that as well. It's good to have a solid, or
at least non-see through cover. Even if a raptor cannot get to them,
it can frighten them so badly they can injure themselves, flying
madly around the enclosure. About the mister or spray bottles, many
don't like them at all. But some will learn to enjoy it so long as
you never spray directly at them. We don't ever want to do that.
Always mist or spray from above so it drifts down on them like rain.
It sounds like you have a good understanding of what they need and
I'm sure that with time, you will all do well.
