I have just moved back into my father's home after being away for a few years. Flock is not doing well, I was always the one who cared for them and I guess after I left they were not given proper attention. Many have died, of what I don’t know. Most of the remaining hens are okay enough aside external parasites which I have treated but one is not so good. Sneeze is a seven year old Oprington or Australorp, maybe and mix. She has a bad bumble and her scale mites have deformed her toes. She has a strange purple patch on her belly and a scab, this might be because she spends alot of time sitting, due to her feet hurting. Her eyes have white patches in them and have bubbles at the side. The coop was dirty and I believe she has ammonia burns on her belly, I have cleaned it since. She doesn’t lay anymore, but she is older so that's not unusual. The other birds look as though they may have a mild case of scale mites but nothing so bad. Here are my questions. Can I treat this Bumblefoot without cutting out the Bumble? Once the scale mites are gone is there anyway I can help her toes into a better position. What can I do about the purple patch? Is it something to be concerned about? Is her skin rotting? Is it just a bruise? Are the white things in her pupil a symptom of something else or is she going blind? What do the bubbles in her eyes mean?
