so, incase anyone ever looks at this thread for a similar problem:
Look in the mouth REAL good, see any yellow stuff? It may be small, but no yellow belongs there. Unfortunatly, I did not get a diagnosis until I had the right person ask me the right questions. I had tried to look in the mouth when she was 1st ill, and I don't think I looked good enough. BTW, it was a difficult thing to do at that point cause she was still fiesty.
Dr chicken told me it is Canker, caused by a protozoan, and it is treated with 1 tablet of Metronidazole (250mg) once daily for 5-10 days. He advised me to tube feed her (since she cannot eat anymore) and I just did for the 1st time. Seems to have gone fabulously, crop is full and although she was VERY stressed cause I took so long, she seems a little brighter.
so....if you have a chicken who fits the bill on this one, feel free to PM or email me if you have any questions I MIGHT be able to answer. I am no means an expert, and hope not to have to do this again, but would be willing to help if I can.
