Well following a thoroughly? wet year last year and a very cold long winter, my two hives were sadly neglegted towards the back end of last year, plenty of food in there but I just couldn't find a dry day or two to do the necessary. So they stayed complete with full supers and an insulation under the roof. There wasn't massive amounts of bees in the hive.
I knew that they would struggle and sure enough a very quick inspection on a dry winters day showed the worst. No survivors!
I left the hives and didn't go back until this morning.
As I attended to the greenhouse before work, I heard a very loud hum.
A swarm had moved in and was occupying the oldest hive!
The front was covered with bees and many were still flying.
I havn't even cleaned out the hive since the winter.
Yes I know. I'm guilty!
I didn't have time this morning to deal with them, so this evening I have just put a nuc on top of the hive with some old frames in there.
I'll see what happens tomorrow.
