My hive is one that I picked up from a retired beekeeper. Apparently a swarm set up shop in one of his abandoned hives. It consisted of a deep and a super. The hive had not been attended in the last 2 yrs. Upon opening the hive I found that the deep contained only 7 frames and the bees had built comb in the free space. I have noticed that my workers are noticeably different sizes, with the larger workers being about 25% larger than the smaller workers (No, they are not robber bees unless they are bringing in pollen to my hive and leaving with honey). Do you think that the bees raised from the "natural" comb have regressed in size, or it normal to have different size worker within the hive due to the different drones that the queen may have mated with? Thanks.
