QUESTION: her hair is missing off of both her front legs. it doesnt look red dry or scaly.

Answer
If the skin doesn't look irritated it most likely isn't fungus.  That leaves fur pulling.  Some chinchillas will pull out their fur when they are stressed.  It could also be something in the cage that she rubbed up against that pulled her fur out.  Do you see any signs of new fur growth in the area?
