Received both packages and installed April 18, Just added my third medium, lower had all brood and a couple honey, upper was all honey. I added another medium under the lower but just as well why could I not add another to the top for more honey production? I was concerned at keeping the brood efficiently in production....Wow! I'm questioning my timing. Last week there was absolutely no honey in that upper. I know it's best to let them do their thing. Hopefully they will build comb quickly! Secretly I was hopping to be able to do a split. My northern most hive is further along than the southern.....saw newly laid eggs, searched for both queens (not found yet) larve, a few drone cells, propolis everywhere....I could have spent hours just looking at everything.
