I purchased a 3# package that arrived 15 Apr and I fed 1:1 syrup for 2 weeks. They consumed about 2.5 quarts and started building comb on 10 bars. I stopped feeding after 2 weeks and they haven't built any new comb in past 3 weeks. The existing comb has capped brood and pollen and I found the queen alive. The total nest is about the size of a basketball. I'm on the PA/MD border and we've already had our peach blossoms.
