The nuc I made from one of my weak hives has brown stains at the entrance. I put half a pollen patty and a pint of Fumadilan-B syrup on top. They haven't touched the syrup, and I haven't checked yet to see if they are consuming the patty. I did provide them with several frames of honey and pollen, though. One thing I did notice is that, although the nuc is well populated, there are few bees flying. The other three strong hives have been flying like crazy! I can only guess that the bees in the nuc are nurse bees, seeing as most of the field bees died due to the bottom board problem I had earlier in the season.
