Hi, I am fairly new to beekeeping only a couple of years in. I had 3 hives going into winter which all seemed to be doing fairly well on last inspection. I recently noticed that the third hive had no activity at
all so I investigated and found that all the bees were dead in the bottom of the hive. I suspect they may
have run out of food but done so very quickly as a few days previously they were fine.
As a result of this I quickly wanted to make sure the other 2 hives were ok, one was very aggressive and did not have a large amount of food so I have fed them some pollen patties and they seem to be ok. The issue is the other hive which a few weeks ago was very active and happy. I wanted to double check on
food in this hive as well and opened it up and found a lot of honey in the frames but hardly any bees, and
they were not active but very slow, there did not seem to be many dead ones anywhere but I did not want
to keep the lid off too long and lose all the heat.
Can anyone give me any ideas about what might be going on with this hive and also what might have killed the other one so quickly ? any help would be gratefully received as I am very upset about it.
thanks and regards
