about a month ago i noticed one of my girls had a sore on her tail. i monitored it for the next few days and another one popped up above it. i cleaned and bandaged both wounds but the next day there was another one below the bandage. i bandaged that one and there was another one above the bandage, and so on until the entire tail was bandaged. it started to smell so i started her on antibiotics and acidophillus and the infected part of the smell seems to have mostly gone away but she is still chewing at it. yesterday i had a work event that caused me to be gone from 6 am to nearly midnight and by the time i got home she had completely chewed a hole in the middle of the bandage as well as a chunk of the tail so it is once again a new wound and a bloody mess. when i tried to get her out so that i could rebandage it, this chinchilla who normally runs to the cage door to see me as soon as i walk in the room tried to attack me. does anyone have any idea what could be causing this? i separated her from the other chinchilla in her cage so it is undoubtedly self inflicted. also, does anyone have any ideas on what else i can do to help it heal? i called the breeder and all she had to offer for advice was exactly what i had already done.
