According to The Virginia House Rabbit Society, rabbits are weaned and ready to eat solid foods by about 8 weeks of age. Baby rabbits should be slowly introduced to hay, pellets, vegetables, and water. For the first week or so, they will only nibble at these new foods. But by 8 weeks old, they should be eating a majority of solid foods and drinking water on their own. If you have any concerns about your rabbit's diet, consult with a veterinarian or experienced rabbit breeder.
