Nicole, given the little information provided, the advice given was to seek immediate vet care. It appears unanimous that all of us posting on the board felt the bird requires urgent vet care.
Everyone assumes she is not receiving medical care because you did not state she is. You also stated that it is not your bird and it is up to your friend to take her to the vet. If she has an apt., surely a vet at the office, even a non-avian vet, can offer some advice in the meantime on what the cause might be, how urgent the situation is, etc. Without knowing more about the bird, other than it is "bloated," how could any of us offer anymore advice than she needs urgent vet care? Personally, if it were my bird, I would not wait till Friday. I would have had a general vet see her immediately, and follow-up with an avian vet. A vet doesnt need to be avian certified to assess whether the situation requires immediate attn., offer antibiotics, etc.
