On July 4th we placed frames of brood and bees in 12 compartments of queen castles and a frame of brood in each of two 5 frame nucs. On the 9th we went through and checked on cells and counted a total of 47 cells. tonight we went back to remove all cells. We startede with the two 5 frame nucs which have both since been moved to 10 frame boxes. We expected to find the original 11 cells. we found a total of 19. This is the good news. Teh story changes as we moved on to the queen castle compartments and that is the pourpose of my post. these castles where built by us and I am suspecting we have a problem with them. The are 2 frame deep compartments with a 1/2 inch diameter hole as an entrance. they have two 1 1/2 inch holes drilled in teh bottom covered with screen for ventilation and are kept in a shady location. It has been hot here with temps reaching 100 plus a bit her for the past few days. In all we found one compartment that had a quen that had already emerged. we found her and all looks well so far. in the other 11 compartments all the cells where missing or at least some cells where missing from the inspection on the 9th. There where orignially 36 cells found in these 12 compartments. today we may have found a grand total of 12. My first suspicion is that the hives are not nearly well ventilated enough but wanted to see if anyone else has any other ideas.
