Why does my parakeet bite sometimes but other times want att

  I've had her for years she used to be nice all the time now she bites hard at random. How can I help her not be aggressive she's always with people and in a huge cage.
You might have been handling her wrongly but female budgies are know for real nasty bites never leaves a skin cut I think so.
my little parakeets really fiesty she might just want a real friend spend 20 bucks and get her one or spend more time with her ... after an hour of holding one any bird calms down a lot mine used to bight me all the time but know shes really sweet .... after i clipped her wings though she doesnt mind too much but her attitude changed dramaticly ... u can find out how to do it online just clip the outer three a little bit
she doesn't like you, but the bird thinks that your the best it's gonna get!
