This is a copy-paste of my first post to you last week -
I don't know if you can get probiotic powder from a vets? Mixed with water and dripped carefully into her mouth it will give her the right bacteria for her stomach. She really needs to also have rehydration salts and intravenous fluids as she may have gone into shock, which could be why she's so quiet now It could be coccidia as that's common in baby rabbits - this is a good article on it

If you can't get the right drugs from a vet she is very unlikely to survive though, and may infect your other rabbits if they share an area, so keep her seperate and disinfect the area she has been in.
It might be a good idea to put the sulfaquinoxaline (I can't remember the exact name - the article mentions it) in the drinking water of the other rabbits, as it will protect them if she does have coccidia - but can a vet give you some? It needs to be mixed one part sulfaquinoxaline to 19 parts water, fresh every day.........'
Also see this extract from Dana Krempels article for antibiotics for coccidia, although your vet might not want to prescribe them without a poo analysis, which takes a week.
..........'The Causes of Runny Stool in Baby Rabbits
1. Weaning Too Young
If the bunny suffering from runny stool is a baby, how old is he? If younger than eight weeks, and not nursing, his runny stool problem may be due to his being weaned too young. Many pet stores will (illegally) sell rabbits younger than eight weeks of age (and some as young as four weeks!), because that is when they are still "cute" and more apt to be purchased on a whim. Sadly, many of these babies will succumb to intestinal disorders.
Unlike most mammals, baby rabbits have a sterile lower intestine until they begin to eat solid food at the age of 3-4 weeks. It is during this time that their intestines are at their most critical phase, and the babies need their mother's milk, which changes pH and provides vital antibodies that help the baby gradually adjust to his changing intestinal environment. Without mother's milk, a baby starting to eat solid food is highly susceptible to enteritis (inflammation of the intestinal lining), which can cause fatal diarrhea.
At the first sign of runny stool in a baby rabbit, off to the vet! Treatment for diarrhea in baby rabbits will probably include subcutaneous fluid thereapy, and administration of oral probiotics. Lactobacillus acidophilus powder (NOT yogurt, which can make the problem worse) suspended in clean drinking water and carefully administered via syringe seems to help foster a healthy intestinal environment and may even soothe intestinal inflammation. A very small amount of a clay-based product such as Kaopectate can help solidify the stool and stop the cycle.
2. Intestial Parasites
As mentioned before, coccidial infection is very common in some areas, and some vets will simply treat a baby rabbit's diarrhea as coccidia, even without a fecal test. Common antibiotics used to treat coccidia include Albon and the potentiated sulfas, such as Trimethoprim Sulfa (TMZ) or Bactrim.
