Colony Expansion

Your new package bees should have plenty of brood by now, and it should be in a tight pattern.  Depending when you got you bees, they might be ready for a second hive box. If not, they will be soon. Beekeepers using 8-frame boxes, Warre boxes, or western supers will all need to put their brood chamber expansion boxes on sooner than those using 10-frame deep boxes.  If your colony is not expanding, look for worker brood on the comb, and look for queen cells toward the center of the frame.  If no worker brood, and if you see queen cells in the middle of the frame (as opposed to the bottom of the frame, you might have a failed queen.) you will need to re-queen immediately.
