Answer
Hi Jordan.
I was unable to determine if this sudden lameness is a new thing or has the baby bunny always been this way since birth? I would have him checked for E. Cuniculi by a good holistic rabbit vet.
Other possible option is Sometimes there are birthing difficulties that deprive the brain of oxygen. This could effect cerebellum motor/balance issues. I have an adult bunny like this myself. But once in motion she is fine. I am not a bunny expert but can he move once in motion?
Please see a good vet to determine possibilities. E. Cuniculi gets passed from mother to baby, some rabbits dont show signs.  
Be sure to keep babies with mom for full 8 weeks, do not wean them in shorter time, this will create many health problems later in their life if they are weaned too quickly.
Also, your vet will recommend she be spayed after babies are weaned.
Thank you for inquiring!
