Welcome xliddobunnyx. You have gotten good advice about the bathing and litter training thing.
I just have some extra things to add:
So are they getting dirty because they sit in the litterbox and eat? It is natural for bunnies to eat while they poop. Are most of their poops soft and mushy which then gets all over the feet and behind? If so, they could be having a diet issue.
What you can try to do to keep their behinds and feet clean is put hay in the box. They can sit on the hay and poop, and many times the their little poops will fall through the hay, and help keep their feet clean. You can also easily remove messy hay and replace it with fresh hay. You may have to do that several times a day.
I have seen many babies, and do understand how they can be messy, but I've never seen it so bad that a bath would be required everyday. So, I am wondering if they are experiencing stomach upsets that would cause them to be extra messy.
