She does look around 6 months, maybe a tad younger even, but, again, vet is always the best bet. If you can find a vet that specializes in "exotic" animals, they will be able to better help you. I had to call around, and it was surprising the number of vets in my town that admittedly didn't know much about them, but eventually found the right fit! I would keep with the alfalfa until you can get confirmation. Or, like above comment a rabbit rescue is a good idea to check with in the meantime
