Back in the middle of July I purchased from a local Bee Keeper 3 Frames of Brood, 1 Queen and several hundred what I thought were Russian Bee Workers. They were all placed in my 8 Frame Hive and stay at the Bee Keepers Yard for several days. Since that time I have been really pouring the Sugar water at a 2:1 ratio in order to get them ready for over wintering.They have done well for themselves have now have 12 frames completed with honey. However, in the last few weeks now I have noticed that my worker bees are no longer a dark black color with black strips. In fact they are smaller in size with a more bright yellowish orange body. More like an Italian Bee. Is it possible that the brood frames I got were from an Italian Hive, and that the Queen was possibly mated by Italian/Ferral Bee which I have now, it seems? I would like to further point out that they have turned mean and do not tolerate anyone just standing around the hive any more. What gives?????
