Did she have any trouble hatching?  I had one that spent all night trying to get out of the egg, and if I recall correctly, she was nearly 3 days old before she could walk properly.  She just seemed really clumsy (and one foot was a little bigger than the other).  She's fine now, but your problem might be something different.  I don't know if there are any medical issues that would cause it.  It's not a leg issue, is it?  (Like spraddle leg?)
