Do you notice any behavioral differences (other than gender-related) or trust issues with your hand-raised vs. parent-raised birds? I've had Cheeky for 5 months, and he's nearly impossible to tame. He still doesn't trust us, and he won't even step up.

I like the idea of fostering birds, and I looked into it recently. There's nothing like that in my area, though, as far as I know. Does Casey form strong attachments to the foster birds or seem to miss them when they are re-homed?
Casey's only strong attachment to another bird was my first conure, a cherry head. Noel had no interest in becoming friends with Casey, and I was fine with that, as I knew Noel could seriously hurt (or worse) Casey. However, Casey wouldn't take "No" for an answer and became buddies with Noel. They often slept together, huddled up. Casey would often preen Noel's head, but never got any preening back. If Noel was eating food out of his foot, Casey would occasionally steal little bites here and there. Noel didn't care.
Since Noel's passing, she just hasn't warmed up to any other bird like she did with Noel. Instead, she views the other birds as part of her flock, and will contact call with them, but if they are simply gone one day, she just goes on about her life. She was hand raised from day one of hatching, from my understanding, so she doesn't exactly know how to "bird". She lays eggs, and she understands she's supposed to sit on them, but she can never figure out how to get a clutch of eggs underneath her, gives up and just walks off. She certainly doesn't understand that in order to get fertile eggs, she needs to be with a male cockatiel, which is all fine and dandy since I'm not interested in breeding and I imagine that if an egg did hatch, she'd probably freak out about the little alien that just showed up that's not supposed to be there!
