Hi, I am a new beekeeper and after having spilt some sugar syrup a few weeks ago i've noticed a lot of mould growing on the crownboard and it's turning black, should i replace the crownboard ASAP ?
oh sorry, the nuc is 2 frame brood 1 frame stores from a previously successful and healthy hive. Just moved into a full size hive and now need to feed in order for the bees to draw out the frames, in the norfolk area of UK.
