The hive with the queen most likely absent has 2 queen cells that are capped on my #5 frame face. Looks like,they turned a regular cell into a queen cell. Definitely not drone cells. They stick out and then bend down almost 90 degrees and are quite large. I have a few drone cells that are bullet capped.
So hopefully they are taking care of it. Of course this starting from a package of 10,000 bees on May 9th they have just started hatching brood today. So this hive is going to gain strength over the next couple of weeks and then have a slow down due to no more eggs since queens demise.
The queen was present during our last check which was 10 days ago. There is uncapped larvae present so I know she was there for a few more days past the last check.
To boost numbers would it be a good idea to put a frame of brood in the queenless hive just to increase population?
