So I received my two nucs a little over two weeks ago. They both appeared to be equal at the time of installation. Well, it wasn't long until I noticed lots less activity on the left hive landing board, so a few days after inspection I check both boxes. The right hive is bursting with bees, has capped brood, nectar, and they are drawing out comb. The left hive has capped brood, not as many bees, nectar, and swarm cells. I checked the right hive earlier in the week, and it was packed with nectar, still bursting with bees, no capped brood, no larvae (I haven't gotten good at spotting eggs yet), and they were drawing out the remaining five frames. I checked the left hive today, and there are maybe enough bees to cover three frames, still swarm cells, some nectar and pollen, but very little capped brood.
I have lots of ideas running through my head on what to do, but it is all a little confusing. From my very limited experience and research, I have one honey bound hive working furiously to make room for the queen to lay, and one hive that could possibly be queenless or with a poorly performing queen. Here are some option I have been weighing:
1. Add a deep box to the strong hive. Move some of the nectar frames to the top deep and add more frames to bottom deep.
2. For the weak hive, take the frame with queen cells and put into a nuc. Add honey frame from other hive for stores. Shake some bees from other hive into nuc. Very little brood available in either hive. Is there enough brood for the split to "take"?
3. Combine the two hives? I really would like to keep at least two hives going.
4. Put weak colony back into nuc until they build up in numbers and reserves. Let them focus on raising brood instead of making wax (?).
I appreciate any and all opinions. Thanks for your help in advance.
(Late addition: Is it too late to contact the supplier and inquire about a replacement queen?)
