Your hives should be at their full operation. You should see lots of nectar and pollen being brought to the hive. You should not be feeding your hive at this time. Brood chambers should be full of eggs and larvae. Make sure your brood boxes are not looking congested as this will encourage swarming.  Your bees should be busy filling honey supers. You can create a small entrance at your supers by drilling a 1″ hole in a super or by adding a small entrance spacer.
