Mine only get a few hours a week INSIDE the cage time. I don't close cage doors. I have a bird room. They come and go as they please... I only lock them up when I'm using cleaner on the floor. I don't want them being "helpful" around cleaning chemicals.
Last night I actually had five out of six on my person at once. (Tusk, Lila and Kiwi on my right arm. Sweepea on my left shoulder. Maggie felt left out, and climbed up on my lap on her own. Pretty much was NOT in a position to say no at that point.) Sat like that playing with them for about an hour or so before putting them back on their playstands. (When you volunteer at a rescue that has 350 birds, all of whom don't get enough socialization, you learn to entertain multiple birds at once. It wasn't uncommon to work with ten at a time out on the big playstand. You get very good, very fast in that situation, or you have ten birds at each other's throats, biting your arms and your face, etc... and you don't get to do it anymore because you just flat lack the skill to control them.) It's not "bird whispering." There's no "wizarding" involved. It's a learned skill. I believe anyone can learn it.
MINE HAVE BEEN EXTENSIVELY SOCIALIZED TOGETHER. THAT'S WHY I CAN DO THINGS LIKE THAT. I've done the work. THIS is my reward. And at times it's just amazing, and at other times it's more overwhelming... would you please just give me some peace now?! (Maggie, my GW, has been especially clingy since my daughter moved out! Kiwi is still very young and is all play, all the time. Tusk and Lila are a set. You don't pick up one without the other. And Pea Pod, like most big macs, wants to be a lap bird as well.)
I did parrot rescue for more than half a decade. People kept giving me birds they didn't want. Most of mine are rehomes, and rehabs. (Except for Tusk, who was a confiscated egg, and Sweepea, my only "breeder bought" bird.)
At one time I had 11 of my own, plus "visiting" fosters, plus I volunteered at a rescue with about 350 birds, and another with about 70-ish birds... (Yeah. I handled pretty much everything. That's how you learn it. Not by watching overpriced "parrot wizard" DVD's.)
