I used to raise rabbits as a kid. We had around 25-35 at one point. Make sure you have a wooden box with clean wood shavings for her to make the nest in. Once the babies are born, keep an eye on them. It rarely happens, but on occasions, certain mothers will reject the babies and even eat them. It's gruesome, but it does happen. It's part of the reason I no longer have them. It was a bit traumatizing as a young child. Generally, once the babies are able to hop out of the box on their own and have their eyes open, they will start to eat solid food. It'll be a few weeks. Don't wait too long to separate them either. Males (bucks) will begin to fight and that can be bad as well. Once they are near grown, always keep the bucks separated unless you want a bloody mess. Good luck.
