Normal or weired rabbit behavior?

Shara is right on everything mentioned. I would also like to add for the mess on her bum, warm water only, shampoos can hurt the rabbit. Usually it will come off by itself but if its bad parasites my come and bother and make it worse, so if its really bad warm water but don't put the rabbit in a tub. just use warm water and a clean cloth and gently wipe the area clean.
