I'm a bit concerned. My little albino budgie, currently 22 days old, is attacking me and his brother every time I put my hand into the nest for them to get used to me. The brother is happy and likes little head scratches, and he's 19 days old-ish.
It's also notable that in my position I cannot hand raise them. As well as that, every time I open the box and mum scurries out, she sits on the perch and screeches at me until DJ (the dad) comes over and calms her. The albino screeches along with her and gets angry at me for going near her.
Temperament is a highly hertiable trait. A screechy nervous hen will often have a nervous screechy baby. That is why selecting quiet natured parents is important if you want quiet natured babies. It may need more time and effort to tame it, but there is usually no need to hand raise a budgie to tame it.
