I'll repeat my post from another list on here, somebody had suggested a bath with a mild dandruff shampoo and feeding the buns flax and black oil sunflower seeds. Shampooing a bunny is not recommended and the diet really won't make much of a difference at all.
I know Kitti responded that the bunnies were treated for mites in the fall and they don't go outside, but fur mites are indoors, it's still very likely mites are the problem and they should see a vet, or at least trytreating them(carefully) with Revolution.

-----------------------------------
I'dhave them checked for fur mites. That's a more common problem in my
experiences, the majority of the time, cheyletiellosis (fur mites) have
been the primary reason for such skin issues. The dry, flakey skin and
balding patches are most often on the neck, back and behind the ears.
Other reasons include fungal or bacterial dermatitis. It really has
to be cultured, a bacterial treatment can feed a fungal problem, so
guesswork isn't so great.
If they're particularly itchy, it can be a mange that can lead to
bigger problems and may even be transferred to humans, so it's really best
to get them checked out.
On the plus side, both the mites and mange readily respond to
parasitic treatments like Revolution or injections of Ivermectin. As much as
I hate chemicals, this is pretty much a standard first course of
treatment. I always have it done at the Vet's office because rabbits can
have bad reactions to almost anything, although the above is generally
considered among the safest. (I'm personally also not a fan of using
shampoos on rabbits, either, the wrong choice can expose a whole lot of
area to a toxic ingredient).
I do think flax seeds and black oil sunflower seeds (as long as the
bunnies' aren't overweight) are very healthy supplements, great for skin
and fur and everything underneath.
