You have some of our most respected people helping you, which is awesome. I just have one more thing to throw out there. Have you checked for abdominal fluid on this girl? I don’t like the color of her urates. Are they really that dingy yellow color (instead of white) in person?
In case it’s worth noting here: I had an otherwise well hen with yellow urates. Suddenly she was pooping black, but I quickly realized she was self-medicating by eating little pieces of black wood charcoal. I also treated her with aloe detox. The urates went back to white after a few days, but I don’t know whether the charcoal or detox helped or if it would have corrected on its own.
