Right now a lot of the state is in a dearth. The bees will be lethargic since there isn't much for them to do. The queen will also reduce the amount of eggs she lays due to lack of food. Were there any eggs? If you have eggs then you have had a queen in the colony in the last 4 days. Putting feed on the colony will help and cause the queen to start laying. Watch for pollen coming in during the morning hours. Feed/syrup and pollen usually means queen is making babies.
