When a baby parakeet bites you does it hurt?

Parakeets bite for many reasons. Did you just get your parakeet and he is scared? Perhaps your parakeet is very protective over a certain toy. It could also be because they are pregnant or are protective of it's other parakeet friend. Are you feeding your parakeet? Cleaning his cage, feeding him things other than seeds? You have to put yourself in your parakeets shoes, because depending on an individual bird they may bite for various reasons.
