Is it normal for a 10 week old parakeet to burry itself?

Yes, it is normal for a 10-week-old parakeet to burrow or hide itself, especially if it's feeling safe and secure. This behavior can be a sign of comfort and can mimic their natural instinct to seek shelter. However, if the bird seems overly withdrawn or shows signs of distress, it may be worth consulting a veterinarian to ensure it's healthy.
