Is it possible that she is egg bound? Feel her abdomen. Is it hard? This could indicate that she is egg bound, in which case you should give her a warm bath. While giving the bath, massage her abdomen. This should help her lay the egg. She could also be an internal egg layer, which would make her abdomen slightly enlarged, and perhaps cause her to walk like a pengiun. However, this is usually a problem in older birds.
What do you mean "she walks funny". Does she stagger, or hold one leg in front of the other? Do you know if she was vaccinated for Marek's Disease? Marek's Disease often starts out with a bird limping, then progresses to paralysis of the legs/wings. Birds can have Marek's Disease for months before succumbing.
Is she lethargic? Worms can cause a bird to be weak, so consider worming her with a broad spectrum dewormer like Safeguard or Valbazen. Check her for mites as well, as large concentrations of external parasites can cause weakness. Look at her legs. Are the scales raised? This might mean scaly leg mites, which can interfere with walking by raising the scales and causing the legs to become crusty. Treat by smothering the mites with petroleum jelly or dipping the legs in oil.
I'd try giving her some vitamins, just in case her trouble walking comes from a vitamin deficiency. Try giving her some electrolytes and probiotics to build her immune system up. Is she getting enough to eat/drink? You may have to consider tube feeding if she isn't eating.
Are the droppings normal? Is there any blood in the droppings, and is she having diarrhea? Blood might indicate Coccidiosis, which would also cause lethargy and sometimes lack of appetite. Green droppings would indicate that she isn't getting enough to eat, or has a problem with her liver, or has a disease called Lymphoid Leukosis (though this disease tends to affect older birds than her).
