Corn, fresh or dried, is NOT safe for rabbits. The hull of corn kernels is composed of a complex polysaccharide (not cellulose and pectin, of which plant cell walls are more commonly composed, and which a rabbit can digest) which rabbits cannot digest. We know of more than one rabbit who suffered intestinal impactions because of the indigestible corn hulls. After emergency medical treatment, when the poor rabbits finally passed the corn, their fecal pellets were nearly solid corn hulls! Those rabbits were lucky.
