Bees are building up

The packages that came on the first  load are building up nicely. New brood has been emerging and I think it is time to add a second box. A second box is needed when the bees have 8 frames drawn or are working on finishing the 8th frame.
One of the frames that the bees are working on (the outside frame with honey or pollen) is removed from the bottom box and added to the second box in the middle of the frames. The bottom box stays at 9 frames. The frame added to the second box is bait for the bees to move up. The entrance reducer is opened to the bigger opening. Feeding syrup is still necessary for the bees to make comb on the new frames.
The bee packages that were on the second delivery should be ready for this in one week. The warm weather coming this week will be ideal for hive development.
