They filled the bottom brood box with honey So I'm running a 3 deep brood chamber setup with a slatted board on the bottom and a screened bottom board. I've added a robbing screen since we have a lot of wasps in this area. I like that the robbing screen allows max air flow and still controls the entrance. Today when I pulled the hive apart to check each box I found that they had packed the bottom box with capped honey. The middle box had arches of honey with open frames below those and the the top had frames with larva. If the top entrance causes problems I'll change as needed. So I put the hive back together with the box with mostly open frames on the bottom, then the one with brood and then the one with capped honey. I added an upper entrance below the box that has only honey. I figured this would put a body of honey between the queen and the supers when we get to that point. The attached pic shows the new configuration. Why would they have filled the bottom box like that and not moved it up to the upper boxes? Should I be concerned about this?
