Hello Martin & all!
Nothing for wory, Martin. I have 3rd generation of 2001. They came with
pollen in January. I didn`t know from where. But today they are very hapy.If
you approach to them, they `ll take rest on your head without any decision
to sting. Reconsider food. Don`t be surpriseg if you find 4 frames full with
brood. Today my fiend - beekeeper found two queen cells. Prepare yourself
for swarming in April.
Have nice day.
