Got back from vacation on 6-20. Worried about how my 6 wk old hives did without me for 9 dys. Opened hives on 21st. (all mediums). 2nd medium drawn out 8 frames seen eggs,nice brood and stores. Added third medium too both hives.Quite a few more bees than when i left. I don't know how they got along without me but they did (Imagine that)
