As a former Rudis breeder, I have had only about 7 clutches in my Rudis days and a few females that I sold as gravid, but yes at about 1-1 1/2 months you should separate them. Remember they are smaller chameleons and as such don't look too big at 1-1 1/2 months but are definetly at the age where they start getting territorial and stress really easy. They reach full growth at around 4-6months depending. That's just a little something to think about. I hope everything works out for you!!
