I think I might have missed the window for applying OA. I went up today when I finally had some time to do it and make sure they were OK for fondant. Would be safe to say that they weren't anywhere near being in a cluster and were not happy to see me, first sting of 2012! I nearly didn't bother with a bee suit but I'm glad common sense prevailed.

Still they're nicely topped up with fondant and I might rethink bailey changing the couple of hives that need new frames to shook swarming them and dosing with OA then perhaps.
