Tried a slatted rack last month and a queen that was easy to find is impossible to locate now.
She is there, because I see all stages of brood and eggs. But she is not visible on the frames. Anyone else experience this with a slatted rack?
I sold the hive and had to leave an F-1 from II breeder queen in the hive (only got 8 F-1 queens from a $250 VSH Italian breeder queen, so this is/was important to change her out with an F-2). Buyer is ten air miles from me so will get some benefit from this queen's progeny (meaning drones) anyway.
