What does it mean when your budgie is just sitting in the cage all the time?

If your budgie is sitting in the cage all the time, it may indicate stress, boredom, or health issues. Budgies are social and active birds, so a lack of movement could suggest they are feeling unwell or are not stimulated enough in their environment. Ensure they have toys, social interaction, and opportunities for exercise. If the behavior persists, consider consulting with an avian veterinarian to rule out any medical problems.
