I saw a similar thread, but my situation is different. I have a laying queen AND what seems to be a laying worker. Both of my hives are package installs with Koehnon and Son cordovan queens. The hives were set up 4/11. The queens have been happily laying and today the first new wave of bees are out and about in the hive. Except in one hive I noticed a single frame with multiple eggs in every cell. Not a shotgun pattern, but every cells radiating out from the center in a solid pattern. The queen is in there because I found her. There are frames with all brood stages including normal eggs. But this one frame, I counted up to 5 eggs in a single cell some attached to the sides. In some of the cells there seemed to be 2 eggs attached end to end like a really long egg but standing up as the eggs do when first laid. I had only been spot checking especially after finding the queen (she is marked so not hard to miss) running around 3 frames over so I went back and look closely at some of the other frames and only see normal egg laying. There are frames that are empty so she isn't out of room. I am not going to shake out the frames because these hives are only 30 days old (25 laying days because it took 4-5 days to let the queen out of her cage). Because I was using drawn comb and had a super of honey for each hive, I put the honey super on instead of feeding sugar to get them going. The queen started laying in the super so I put an excluder on. The first wave of new bees came out of the honey super and there are no eggs, not even multi-egg cells in the super now (still some capped brood). The multi-egg frame is in the brood box where the queen is. I read that new queens sometimes lay multiple eggs in a cell as they first start out, but my queen has been laying for the last 25 days with no issues. As I mentioned, there are empty frames of drawn comb in the brood box just waiting for her. The population is very low right now and most of it seems to be up in the super.
