I have a hive that has been queenless for sometime (about +45 days) and I just received a queen yesterday. I immediately installed the cage, but first took a few minutes to observe the hive's reaction to her.
I couldn't ever get a vibe from the hive whether they were excited or angry, but definitely a reaction. I have been expecting a laying worker situation since they have been queenless for so long, which may cause rejection of this new queen. Could someone with more experience with re-queening provide feedback or thoughts?
