I don't know if it will help or not, but when I have had sick chickens (no matter what disease it appeared they had) I would mash up some fresh garlic with some fresh curare (you must have that in your area) and a bit of olive oil to liquify it a bit, and drop it into their mouths ... a few drops a few times a day. I don't know if it was the cure or the fact that they would have recovered on their own, but I never lost a chicken to disease. Speckles is beautiful ... I hope she recovers.
