In the upper box of 2 stacked boxes, the bees have built a comb structure to the side of the foundation, rather than on it. The supports linking the comb to the frame attach to the frame and the foundation in just a few small places (most of the connections are hidden under the comb). The result is two-sided comb, with bees working both sides. To access the "inner" side, the bees are crawling between the comb and the foundation. The comb is already in use for hoeny production. Other facts that may or may not be relevant: the foundation is black, the top boxes have been on less than 2 weeks and the colony is very active. Should I be concerned about this comb structure?
