Pipp: Sorry I didn't reply sooner to this. My rabbits had ear mites and they both were treated with Ivermectin, an injection every two weeks for the ear mites. My vet suggested that I clean my rabbits ears with water and kleenex. I have been using a cotton swab and very carefully clean the inside of their ears. I always measure to see how far down I can go before I hit the ear drum and I never have hit the ear drum. Be careful when you clean the inside of the ears you don't hit the ear drum otherwise as my vet says will be more problems.
Now my rabbits are almost ear mite free, they still have a tiny bit left but their immune systems are taking care of the ear mites. Also let your rabbit exercise, it does help the immune system have a fighting chance at getting rid of the ear mites. The immune system can only get rid of ear mites when the ear mites are in the very early stages.
Ivermectin took care of the ear mites in my rabbits with only two injections each.
Oh I would separate your flemish from the other rabbits so that they don't get ear mites as well. But if your flemmie is bonded make sure he/she can see the other rabbits and talk to them so that the bond can stay between them. My two rabbits are still bonded even after being separated because I kept them within talking range and seeing range when they had ear mites. Now they are in their rabbit area playing together and sitting next to each other. I had them out of their cages all night last night because they were so good at their check up yesterday. That is how I found out that their ear mites are almost totally gone, they only have a little bit(tiny bit)!
Hope that your flemmie gets better and gets rid of those ear mites!
