I would add blueberries to secondary, pre-frozen and thawed so you can extract the most out of them. BE CAREFUL though, i haven't had a single blueberry beer that i've like. The sugars will ferment out and leave it with a tart flavor. I would also purchase blueberry extract and at bottling add little by little to get the desired flavor.
