Answer
You really need to get her to a vet.  She may be egg bound.  This is a serious condition that is fatal if untreated.  Call an avian vet and tell them that it is an emergency and you need to get her taken in to help get the egg to pass.  Meanwhile, there is not much you can do.  Take some vegetable or mineral oil and put it on her vent (the opening of her rump).  Then put her in her cage in the bathroom and run a very hot shower.  The heat and humidity may make it easier for the egg to pass and this can sometimes get a difficult egg to come out, but I can't guarantee it and you really need to take her to a vet to make sure that she's alright.
