Baby rabbits, also known as kits, should typically be weaned between 4 and 8 weeks of age. The exact timing of weaning can depend on the breed, individual growth and development, and the mother's behavior.

The weaning process involves gradually introducing solid food to the kits while reducing their dependency on the mother's milk. Here's a general guideline for the weaning process:

1. Introduce solid food: Starting around 3 weeks of age, you can begin offering small amounts of high-quality rabbit pellets, fresh hay, and fresh vegetables. Offer these foods in shallow dishes or scattered on the floor of the enclosure, making it easily accessible for the kits.

2. Monitor the kits' response: Watch how the kits interact with the solid food. They may initially show curiosity and nibble on the new items. As they grow more accustomed to solid food, they will consume more.

3. Gradually reduce milk intake: While introducing solid food, the kits will still nurse from their mother. However, you may notice that they spend less time nursing as they eat more solid food. This natural progression helps transition them away from milk gradually.

4. Separate the kits from the mother: Around 6 to 8 weeks of age, you can begin separating the kits from their mother. This allows the mother's milk production to naturally decrease, and it encourages the kits to become more independent.

It's important to monitor the kits' progress during the weaning process and ensure they are eating enough solid food to meet their nutritional needs. If you have any concerns or questions, consult with a veterinarian who can provide guidance based on the specific needs of your rabbit breed and the condition of the kits.
