Most did, like in Halo 2, we just didn't see any because Bungie didn't want to confuse players with having enemy and friendly Grunts. The same goes for the Hunters, practically all of them joined the Elites. I think the Grunts were probably more evenly split, they're a simple-minded race and work for whoever scares them more. They're believe almost anything they're told by a higher-ranking Covie.
