yes i do have other rabbits. thanks for the reply, but I don't think it is I've been looking at some pics and it's much different. Its more just a few tint amounts of crust than varices different bigger patches. But I guess it could be. he is a Holland lop though his ears did not lop.Can't see much on the picture, but could be vent disease (rabbit syphilis). If you have other rabbits keep him quarentined and see a vet, if it is that he would need an antibiotic treatment.
