Worried from Elvaston....

Noticed a distinct lack of activity around my second hive (the climbing frame swarm) over the last few days, very low numbers going in & out, not an encouraging sign.  Was going to go out this evening for a look in, but since we're in the midst of a torrential downpour & thunderstorm, it will have to wait until tomorrow evening.  Thankfully, the other hive still appears to be thriving.  Will update again......
