Activity in all 5 city hives (December 2017)

Storm Caroline blew through overnight. It was worst in Scotland but we had higher winds. All 5 hives in my out apiary stayed upright. During my check this morning I also found evidence of activity in all 5: brood and honey cell cappings on the hive floor. The entrances are all clear.

I hefted and found that Hive E is a bit light. I really need a comparison. The complete Commercial hive weighs at least 20Kg according to Thorne. The guidance is that a colony needs 25Kg to see it through the winter. I don't think that Hive E has enough. I'm not sure about the others. Luckily I've held back some solid honey which I can give to them.
