When I was a kid my dad brought a young budgie home from one of his workmates who bred them, it was a grotty looking grey female with an undershot beak that had to be trimmed regularly. He called her Beauty! My mother hated fluttering birds around her so had to leave the room when 'Beauty' was let out to fly around. She didn't like the piles of seed on the carpet either.
One of our aged neighbours had several budgies flying free in her house, one day her half blind husband sat on one and killed it.
