If your bees are on a good flow they will draw wax...
You can extract those frames, and put them back on the hives the next day, or let them draw new frames out.. If you want to feed, go ahead and feed, but once they get those frames well started,, three or four of them ready, then pull the feed..
Another trick Iddee once stated, was to use feeder jars with only three or four small holes in them, as opposed to the jar lids with 20 plus holes.. it means they still get some syrup, but not enough to store, so they use it all to feed and to make wax with..
