It happened. I went to check my bees today because my dad was concerned he hadn't seen any flying around one of the hives today. I assumed quite laissez faire that it was nothing to worry out, it's borderline too cold for bees to be flying any way. But I put on my gloves and headed up to check all the same. First thing I'm met by, the sight of diarrhoea sprayed all up and down the entrance of one of my hives. Now I know I've posted before that I thought my colonies had died a winter or two ago....
