3 colonies dead, 7 still going strong
Today was very warm, 7'C but it must have been warmer in the sun. Most of the colonies were flying except 3 hives so I decided to gently open up these hives and see whats up.
After opening the first hive I heard no buzz, so I knew something was wrong. I removed all the combs and found dead bees all over the combs and hive floor. It was easy to see what happened here; the brown strokes on the hive wall is bee poo/feces and is a sure sign of a disease called Nosema. Healthy bees don't waste inside the hive but do so outside on sunny days, so called Cleansing Flights. The dead colonies are 2 last year swarms from my apiary and a split with the old queen.

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.
