Hey - new beekeeper from Western Australia here.
I have two new nucs I'm starting with and progress is so far in the past two months has been negligible.
I am feeding a 1+1 sugar syrup, in inverted jars on the crown board. I noticed that syrup has developed black strands in it and looks like it's gone mouldy. I of course discarded it.
My questions are:
1. the bees have been consuming this mouldy syrup, and whether that is detrimental for their health,
2. what I should do and look for to make sure they are not sick,
3. and how can I keep it form going mouldy again in just a few days.
