Looks normal.
If a het could be told from a normal by looking, then the trait would not be considered recessive. (A visual heterozygous trait would make it co-dominant).
So, while there are some common markers in some heterozygous animals for some morphs, none of them are 100% conclusive, or always present.
You simply can't tell whether she is het pied until you breed her to an animal carrying the pied gene.
You should always get paperwork, and information on the original breeder, when buying a het (at least, if you're paying more than you would for a normal).
