Here is a close up of the bee feces (brown stuff)
Here you can see bee feces on the comb and some bees are sticking inside the combs which usually is sign of starvation but this is out of question because there is lots of capped honey just beside them and they sure had at least 6kg of stores left.
all 3 hives had the same issue with Nosema
Dead bees clustering around a dead queen (can you see her)
Lots of stores left in these hive but I can cant give it to the other colonies because they are infected with Nosema spores. Pity really. Lets see if the other colonies can pull it off until the first spring blooms.
