I got a swarm out from a old dead tree. I somehow killed the queen in the transfer. I ordered a queen which was not marked or clipped, in a week or two I went in to see if she was out of her cage. She was, I seen her fly off of the frame she was on never to return, with alot of my worker bees. I still had a small swarm, so this time I ordered a queen that was marked and clipped. I checked in a week to see if she was doing ok, and she was, I check again in about three weeks later, and see was laying eggs that's been a month or so back. I thought I would look back in yesterday evening to see how things were going. I could not find the marked queen, so this morning while I had better light, I went back to see if I could find her. I did not find her but a different queen, I am positive it was a new queen, no dought. My concern is this, out of all the times that I've been dealing with this swarm I have never seen a drone in this hive, and this is the only hive I have. I am not seeing any new queen productivity at all. If a swarm does not have any drones what can the queen do to become fertile? Should I requeen again? to make sure I have a fertile queen? Also one other question. What made this swarm replace this new marked, clipped queen which was working, so quick? do you think maybe the bees seen her as inferior since she was clipped, and they needed to replace her with a queen that could fly. Need some advice since this new queen is not laying at all.
