Yeah, I found an "all flock" feed that's 17% protein and only about 2% calcium, so I'm going to feed her that, and I'm considering switching the whole flock to that, because now I'm worried some of the others might get gout, too. Our soil here has a lot of calcium, and they have oyster shells to eat if they need to, so presumably anyone still laying will be okay.
She definitely has foot gout, her feet look pretty bad. But what worries me is she's having very watery poops, and diarrhea is apparently a symptom of visceral gout, not articular. Supposedly the only way to know whether they have visceral or not is after they die :\
We took her to our avian vet today, and she didn't want to prescribe an anti inflammatory because it would stress the kidneys, but she did give us a pain medication. I think Fleur is in some pain, but not too much, thankfully. She's mostly acting normally, except for drinking a ton and having some trouble staying warm, and laying down a bit more than the others. But she's seemed...relatively low-energy, compared to the others, for many years, so I'm not sure if that's part of the gout. Maybe she's had the beginnings of gout all these years :\
Vet didn't prescribe any gout-specific medication, but she gave us some at-home things to do: flax seed oil mixed with a little corn oil every day, and beta carotene every day. We did bloodwork to test how well her kidneys are functioning, and we'll get the results on Tuesday. Maybe she'll prescribe something then, but I'm not sure.
