Dobby gets Zupreem fruit blend pellets, Nutri Berries, and whatever we can come up with that he likes. He gets some of dinner usually and like that too.
He likes apples and walnuts, just tried and liked grapes, sometimes he likes brocoli, tomatoes, banana if he can sneak up and punch holes in them to steal the fruit, lettuce and of course any bad for him junk food if he can get it.
Nerd loved raw brocoli and peanuts but peanut it turns out was a bad thing for him so we avoid them now even though he made 31 years with us. Lurch loved walnuts, apples, carrots, potatoes, rice etc.
They usually love toys they can beat up on or make noise with like bells and safe string or rope sisal ball. They usually love showers or baths too, just run a vacuum and many will get right into shower mode.
They remind me of a feathered cat, happy to hang out by you and get scritches and maybe a treat once and a while.
Every bird is their own soul so it varies and you two will come to a understanding with time. Some can take years to let you earn their trust, some will pick you and be your friend quickly so be prepared for a long haul just in case. Once they decide your worthy you'll have a loyal friend for the rest of their life.
