I thought so too, but i will wait until the temperatures are more bee friendly, Sunday at least or maybe Tuesday. When refilling the syrup yesterday they all were huddled up in the brood box.Since you direct released the queen I would think that you will have capped brood by next weekend. You could wait until then or do a quick inspection this weekend for eggs. You dont need to smoke them, just start from the outside frame and move in until you see eggs. Put the frames back and close them up. You can do simple inspections like that once a week.
