As long as your chinchilla is eating, drinking, and behaving normally other times of the day, there is no cause for concern. If you are concerned about your chinchilla's behavior, it is always a good idea to consult with a veterinarian.
Is it bad if chinchillas are laying down all the time?
No, it is not necessarily bad if chinchillas are laying down all the time. Chinchillas are crepuscular, meaning they are most active at dawn and dusk. During the day, it is normal for them to spend a lot of time resting and laying down.
