I had a look through one hive and pulled two foundationless drone frames to check for mites. Cant remember how I came to have two. I uncapped and pulled both sides of one frame and did not see any sign of mites. Some came out mess up but lots of intact snow larvae with nary a speckle. That is the hive that was overrun last summer and had poor laying pattern. She is doing well this year and gave some frames to the neighbour hive that went queenless but that hive always is later to start in the morning and so I am requeening that one and the neighbour that requeened itself. If I had more bees I would start a couple of nucs with the old queens but prefer to get some of the new genetics in the mix as there are no other bees than mine within flying distance. I noticed remarkably little burr and brace comb; that might be a result of lettting them draw and fill lots of drone comb. It also could have something to do with perhaps different genetics of that queen. 1 is a very small sample to base a conclusion on!
