Karin is a new beekeeper. She got a split from me with a daughter of the swarm that came from the wall of one of her houses, an unheated older, kind of summerhouse. http://www.elgon.es/diary/?p=515
At the end of last summer, the new colony had grown strongly to three square shallow boxes. Then came the heather flow (Calluna vulgaris) and the bees filled a super above the queen excluder (the forth square shallow) with almost 20 kg of this thixotropic strong honey. And it collected about the same amount in the winter room (the three boxes). This honey is said to be difficult for bees to use as winter food.
It appeared a few wingless bees after harvest and this colony was the only of Karin had so as precaution it got 2 pieces thymol of dishcloth with thymol (2 x 5g) with about 12 kg of sugar in solution.
The colony has been sitting still during winter, and heavy of feed. Some bees made a cleansing flight first week of March. It is visible on the hive top. Today, March 13th, we checked the colony together. With a long stick we scraped out a handful of dead bees. Not a bee came out and asked what we were doing. They sat still again. Temperature 36°F (2 °C) outside.
As we watched the bee cluster through a plastic sheet cover the bees sat quite tight but it was on the middle of the cluster. The bees have brood. We felt the weight. Lifted on one end of the hive and then the other. The colony was still heavy, but noticeably lighter than the last time we checked the weight. It has apparently made some brood during late winter/early spring. And it smells heather honey from the entrance of the hive. The colony is strong and looks very promising.
