I don't know what would be causing the flaky skin... as for the fur, it could be molting or it could be mites... hard to say without a pic.
you can upload pics to photobucket and then copy/paste the image link, or you can upload them to the RO gallery... if you use the RO gallery, you need to click "reply" instead of using the quick reply box. there's a big G on the far right end of the lower menu bar - click it and it'll pull up your gallery pics so you can link to them in your post.
revolution works really well on bunnies to get rid of mites and such (you have to get it from a vet but you usually don't have to actually take the bunny in for an appointment). advantage also works. NEVER use frontline - it can kill a bunny.
