i just wanted to say i'm so sorry this happened to your lil girl. The poor thing, i hope she feel better real soon!
Can i just ask what causes a ruptured eardrum?
In mini chick's case she got a cold a few weeks ago. Doctor said that during this cold she got a build up of fluid behind her eardrum and it never got released so the pressure kept building up. She then got ear infections (in both ears actually) and obviously that was the straw that broke the camel's back and bam there you go poppity pop. It's pretty ordinary. I didn't realise how common it was though.
