You may have posted it before and I just don't remember, but did you get Ocean as a baby or not and do you know her age?
I am concerned that this may be diabetes and it also sounds like there may also be some sort of yeast infection. I can't be sure, but I think diabetes is normally caused by dietary issues and perhaps this can be controlled through diet as well, if it does turn out to be diabetes. I have never know a bird with this problem, so am going to have to do a lot of research if I hope to be helpful. I think that raw apple cider vinegar might be useful in combatting a yeast infection as well as probably watching carbohydrate sources and amounts. Again this is just off the top of my head, wish I knew more. Please keep us updated.
