Rice can't swell without water and it won't get any bigger than the combined volume of dry rice and water. So if the bird has room in his "Tummy" (I can't feel serious about the opinion of anyone who talks like that concerning health issues; they really sound like they don't have a clue) to add water to the dry rice, then he has room for the rice to absorb the water and expand.
Even if you add a little bunson burner to his "tummy" because rice absorbs water a lot better if the water is boiling. Ask any cook how well raw rice becomes nice and fluffy if you soak it in cold water.
