It was about 8 degrees C when I inspected my three colonies last week.
I was expecting one or more to be dead, given the very harsh winter, but all three were very much alive.
It was a bit late, but I gave them their Oxalic Acid treatment.
Two colonies were very docile, but the third was very aggressive. I wore just a smock top and several bees burrowed into my pocket and stung me through the lining. Luckily, just my leg. Could have been worse.
This colony has always been feisty, even though they superseded the queen last autumn. I was hoping their disposition would improve.
This is the colony that I might move. It produced no excess honey last year and I think it's because it is just too exposed a position. They had plenty to eat, with a field of Oil Seed Rape just next door. But they never thrived.
