Thank you chinclub for your answer and the way you try to put things down!
"OK, first lets be sure it is the fungus because dusting a chinchilla everyday will cause dry skin on the ears and feet. You could be causing the symptoms you are trying to treat."
You are absolutely right and that is what i want to know. I really try hard to find if it is fungus or something else... Unfortunately there is no vet where I live to know from chinchillas and also to do blood tests or microscopic faecal examinations and cultures. Feces culture as I know needs a week and maybe more, though, to have results. I hope it is not fungus, but I react at the moment as it is fungus. I know how bad it is to be fungus and how important the care is before time shows real and bad results...
"The one with fur loss on the nose. Is the baldness spreading? Is the exposed skin red or the normal color? Do you see any signs of new fur growth? If the baldness isn't growing, the skin looks normal, and new hair is growing it is not fungus. If the skin looks red and scaly, if the baldness is spreading it is fungus."
The baldness spreaded as I can see but only to the spot he started to loose fur. It didn't become bigger. It is not red but his normal color (grey most). I can't say if hair is growing, today is the fourth day and maybe is early. Because the baldness is exactly at the start of his nose and upper like 4mm, the skin is a little pinky where his whiskers are but that is normal, i think, not sure.
"Were the two males (fur loss and eye trouble) housed together or in separate cages? If they were housed together I would consider that is was a fight than caused both problems."
They housed together with a third one too. I am not sure that it was a fighting because the one with the baldness is my first chinchilla, he is 7 years old and is extremely calm and good, never fights. But you can never be sure what happens at night when you sleep though... The other one with the eye problem for 4 days i was using chamomille to his eye 2 times a day and the eye was going much better. The white discharge was gone from the second day and it was almost 90% opened yestarday so I thought that no antibiotics will be needed. Suddenly though, today morning his eye was shut, sticked with the white tearing and i used warm chamomille to soft it and so to open the eye, and i started antibiotic drops now to his eye so i think that this is infection too like conjunctivitis.
I know that the situation is a little condused and thats the reason I opened the thread. I am lost and i don't know what I have to deal with exactly. Maybe time will show, but I try to find the cause and the treatment before time really shows and I am scared about myself too, as I know that IF it is fungus it can be spread on me too. I try to take all precautions like wearing other clothes, epsecially with the grey one that has baldness, and wash my hands good etc.
