I wouldn't attribute the slugs/stillborns to the fact she was a first time breeder. More likely it has something to do with stress and/or environmental factors (temps, etc...). I have never had first time breeders slug out, but have had animals slug out that were a little too thin to breed, or shipped while gravid.
