I had two boxes which were not progressing this spring as the other boxes. In fact, no eggs/larva at all. I added frames of brood to them. After the queen cells had formed, I added 2 extra frames of brood to the fairly decent hive, to give them a boost. (I could not locate a queen in other donor hives for the other one and so didn't add any to it). After waiting the number of days, one (without the added brood) had capped brood, larva, and eggs most everywhere. The one (with added brood) had a small cluster of drone cells, and multiple eggs in a few cells nearby.
Question: Did adding the 2 frames of brood to about 8 frames of bees (I added them to the box below the bees already in the box above) kill the queen cell or queen?
Thanks to previous advice, and experience, I wasn't going to mess with it any more. The latest expected date for egg laying was the 8th, and this was the 23rd. Either they didn't have a queen, or something was lacking in her. And the other box was doing fine. So I removed the box to another area, shook the bees out, added the frames to other boxes, and then saw the bees form a cluster in a nearby cedar tree. In a previous shakeout, the bees dispersed. I noticed them clustering early, and looked closely for a queen, but did not see one. Today, a day later, I see them still in a small cluster.
Question: Does this mean there was a queen? Would bees cluster with laying workers?
