Hello everyone. It has been some time since I have asked the forum questions. I am in my second year of beekeeping and not having too much luck. I lost my last years population during the winter to unknown causes. I got a 3# package this last April but had no luck. The package that I got dwindled down to a population of about 200 bees at present. The queen is still in the hive with the few bees staying. I purchased a deep 5 frame Nuc from a local beekeeper. When I picked them up the seller made sure that I had at least 4 to 5 lbs of bees with the five frames of brood, nectar, honey, pollen, and a good looking queen. I have had the bees for about one week and I have noticed a big population die off. Bees being cleaned out of the hive, and at least 1,000 or so bees spread out all around the hive. I checked the fresh dead bees and found not mites and the hive beetles are very few. I opened up the top of the hive today and there were a lot of bees on top of the frames. Friday I am going to open and pull frames to find the queen and calculate the population. Since I am new to Nucs, is this die off normal? Any comments or ideas would be appreciated.
